“Most people give up because everyone has told them what they can’t do, and it’s easier to stay safe in the comfort zone. So they sit on the fence, unable to decide, unable to act.
But if you don’t make a choice, the choice will be made for you.
It’s time to stop listening to what everyone else says about you, telling you what to do, how to act, how you should feel. Let them judge you by your results, and nothing else; it’s none of their business how you get where you’re going. If you’re relentless, there is no halfway, no could or should or maybe. Don’t tell me the glass is half-full or half-empty; you either have something in that glass or you don’t.
Decide. Commit. Act. Succeed. Repeat.”
