Wise words from among many that Amazon CEO Jeff Bezos has said:
"If you only do things where you know the answer in advance, your company goes away."
Probably true, too, with your work, relationships, and personal endeavors. When you only do the things you're sure of, where you know exactly what will happen, how can you grow?
Take the risk. Ask the question. Search for the answer. Try again.
I don't know of another formula that will take you somewhere new.
