Costa Rica: Manuel Antonio National Forest

The monkey isn't amused.

Mary Perfitt-Nelson's insight:

I just returned from spring break with my daughter in Costa Rica.  It was just the two of us.  We were on a mission to see the animals we've read about for years.  Most pressing was the three-toed sloth.

First off, we found  the people we met in Costa Rica to be genuinely warm and welcoming.  The people were indeed one of the biggest pearls of our trip.

We rented a car and made the 3.5 hour trek over to the Pacific Coast from San Jose.  At one point, scarlett macaws flew over our car.  Quepos was the last small (and vibrant) town before we made it up the mountain into the Manuel Antonio section.  Out hotel was at the bottom of the mountain near the ocean and entrance to the National Park.  We paid only 80.00 nightly during high time; we were cared for well by the hotel staff at Hotel Verde Mar http://www.verdemar.com/. &nbsp;  This was not a pricey hotel; it was clean and neat.  The people went out of their way to make our trip wonderful.  We have nothing but positive things to say!

Over the next week, we divided our time bewteen the National Park, other adventures, eating and swimming.  We did the ziplines over the canopy, learned how to surf and had an amazing ride on horse through streams and to waterfalls http://www.verdemar.com/pages/activities.html.&nbsp; The water and beach was pristine.  The food was amazing  http://www.ronnysplace.com          Coffe was fantabulous.  http://www.cafemilagro.com/restaurant/.&nbsp;   We saw numerous indigenous birds; reptile and troops of three variteies of monkey.  And yes, we saw many sloths in a variety of unusual places.  Cab drivers have GREAT eyes for sloths!

Flights were about 600.00 total , per person.  We used Travelocity and found them less expensive when you purchase two one-way tickets.  American Airlines had new planes with comfortable seats and NO charge for baggage.  Spirit, however, charged 45.00 per bag each way and the seats were quite uncomfortable.

I love Costa Rica and will definitely go back!

Inter-Cooperative Council

Student owned and operated since 1932, the Inter-Cooperative Council at the University of Michigan provides affordable housing for students that embodies quality living, community and social equality, all within the cooperative movement.
Mary Perfitt-Nelson's insight:

Parents of college kids:  this is something you MUST know about!  Co-Op living on university campuses can happen everywhere.  The benefits are huge!

This is where my son lives.  The monthly rent is a fraction of the cost for dorms and other housing on campus.  It includes food.  The kids work together cooperatively to clean, cook and keep the house running smoothly.  They become a tribe.

Unexpectedly, there are co-ops across the country and internationally.   Kids travelling can contact a house and most often they can stay a few days for free!

My son just returned from Toronto where he stayed FOC at a co-op.  The kids there took him under their wing:  showed him around town and  invited to their dinners.  Thanks to them, his trip was phenomenal (and CHEAP!).  He plans to make more roadtrips to campuses all over the place.

Pocket Knives, Warts and Refrigerators

Mary Perfitt-Nelson's insight:

I completely LOVE this story by Kerry Weeks about his experience with coincidence via pocket knives, warts and refrigerators.  I can completely relate to his difficulties KNOWING when to believe things.  Like Kerry, I think in possibilities.

"I was the son of a physicist.  I better than most children had an idea of just how VAST the universe is and therefore how INFINITE the possibilities are."

Heard the story on NPR and giggled away.

Pocket knives are wonderful, btw! Gotta have a few, just in case.

What Data Can’t Do

Data can’t account for everything in our experience, nor serve as the only guide for our thinking, planning and decision-making.
Mary Perfitt-Nelson's insight:

This is not to argue that big data isn’t a great tool. It’s just that, like any tool, it’s good at some things and not at others. As the Yale professor Edward Tufte has said, “The world is much more interesting than any one discipline.”

Taking my daughter to Costa Rica in two months for her senior spring break!  She, like me, is fascinated with wildlife.  We will spend a great deal of time in the tropical  forest hoping to view a sloth or two.  I am very excited to have this time with Madeline.  She is the lead on our planning.

Raising Personable Children, Even If They're Glued To Phones : NPR

Technology is ever-present in the Jordan household. But Sue and David also want to make sure their five kids know how to relate to each other in person.
Mary Perfitt-Nelson's insight:

Now here is the conundrum (if you are raising teens).  The tech thing.  How to put limits and assure everyone that your kids can have conversations f2f.

I know of parents doing all kinds of things:  taking phones at 9pm, avoiding getting phones for kids, having kids turn them in at family functions, etc.

With everything:  moderation.  Frequency, intensity and place are the factors to monitor.  Limits are good as they help grow self-control.

And then they turn 18 and it's up to them.............

Your Children are not Your Children, Kahlil Gibran

Famous Kahlil Gibran quote.
Mary Perfitt-Nelson's insight:

Powerful reminder for parents (and teachers).

Embracing this allows us to truly be their coaches; their cheerleaders; the voice in their head while they are alone urging them to take a chance.  Our role is one that helps them discover what matters to them; help them find and use their voice.

Kids say the darnedest things!

Mary Perfitt-Nelson's insight:

My nephew is 3.5 and crazy about astronauts and space.  He is reading with my sister when he asks:  "Are astronauts mammals, too?"  My sister says yes, of course.

He stares at the picture of several astronauts (all balding) and says:  "But none of these guys have any hair."

My sister preceded to stop herself from explaining male pattern baldness to her three year old.

The Market Speaks

Yes, the Dow Jones industrial average has been setting new records this week, but the message from the markets is actually not a happy one.
Mary Perfitt-Nelson's insight:

"The important point about these particular bad predictions is that they came from people who constantly invoke the potential wrath of the markets as a reason we must follow their policy advice."

"What the markets are clearly saying, however, is that the fears and prejudices that have dominated Washington discussion for years are entirely misguided."

Surprise, surprise:  Chicken Little was wrong.

Black swan and koi

Mary Perfitt-Nelson's insight:

A black swan feeds its fish friends every day to the amazement of passers by.The swan picks up the feed and takes it to the mouths of the waiting fish.They became close friends after 3 years of playing together, Every time he comes to feed the swan, all the fish follow him to the bank, with mouths open. And he takes the food and puts some into each of the hungry mouths.When everyone has eaten enough, the swan goes back onto the water and plays with his fish friends again.

How Did Our Brains Evolve To Equate Food With Love? : NPR

Until recently, our brains' way of connecting food with love and a sense of well-being was purely a good thing. But in a world where it's possible to feast every day, it can be a problem.
Mary Perfitt-Nelson's insight:

Working with unattached kids, one tip is to offer them food with your hand.  As they take it, pause before letting go.  Look them in the eyes.  They will connect food and love with a human.

Thinking vs. Knowing: When Facts Get in the Way

‘Knowing’ is often a crutch for ‘thinking,’ suggests author. That can have bad consequences when we accept those shortcuts in leadership.
Mary Perfitt-Nelson's insight:

Memorizing facts, procedures and routines is not thinking.  We rob thinking when we stay at the knowledge level.
