This discussion seems to be always too hard.
I am coming to realize that regardless of being profitable or not, doing what you love is the way to go.
Don't know what you wanna be when you grow up? Well... pick what you like to do most at this very same moment and go for it.
If you change your mind, you then can decide whether you should quit again and pursuit something else.
Another good reading on this line of thought is "The Dip" by Seth Godin.
Please fail. And fail a lot. But be sure you get into something because you love it and are willing to work hard for it to overcome the difficulties. Otherwise it may not be worth investing your time in it.
***** Agree. I left corporate America after reading Your Money Or Your Life to start FoundObjects.com (now RIP). Ever play with magnetic words on a refrigerator or locker? Chances are our specialty gift company sold Magnetic Poetry Kit to the specialty gift store you purchased them from - so our company touched millions of people. Then we failed, but creating one of the first B2C and B2B websites meant I found a job in this new thing called Internet marketing as a Director of Ecommerce. I loved selling things online and helped my employers make millions.
Then I quit to ride a bicycle across America because, as a cancer survivor, I know life is not an infinite journey :). Got home from a 3,000 mile bicycle ride and found a great job as a Director of Internet Marketing for Raleigh web developers Atlantic BT. Somehow things work out, so Do What You Love and The Money Will Follow (another good book). I agree with The Dip as being a great, fast read on the importance of knowing if you are in a dip or at a dead end.
Inspirational Scoop. Thanks.
