Decisions.

"We can think about things, turn them over in our minds a million times, play out possible scenarios, but really when it comes down to it, you have to go with your heart and move forward. maybe things will go well. Maybe they'll turn out poorly. Every decision brings with it some good, some bad, some lessons, and some luck. The only thing that's for sure is that indecision steals many years from many people who wind up wishing they'd just had the courage to leap."
