A breakthrough is an event that changes everything; when it happens, you get to the next level, and nothing is the same from that point on.
Breakthroughs happen rarely, and they have a tremendous impact on our lives.
Can a breakthrough be forced? Provoked? Created? Unlikely. But you can certainly improve your chances of finding a breakthrough if you start actively looking for one.
When you stumble, reflect on it and see if you can uncover the deeper meaning that lets you understand the underlying reasons for the failure. Something unexpected works? Try to figure out why, and you just might find your next breakthrough that changes everything.
