With a few small changes in your mindset, you can turn rejection into a dramatic boost for your motivation and focus.
Being rejected is often a statement that you (or your ideas) are too far from the current mainstream to be considered safe or comfortable. This could actually be a good thing. You're ahead of your time. While the group or client may not believe they need you right away, the world probably does. If you're too far from the mainstream, you could be the one pushing progress forward.
