I once read a piece of advice that said: Do one thing every day that scares you. Not exactly a safe way to go through life, but then again, that shouldn’t be our goal.
Growth can be frightening. Going after something you really want can scare you senseless, but leave you exhilarated at the same time. And I think that’s called being really alive. Staying in one place (figuratively or literally) doesn’t give us the chance to grow. You can’t follow your dream if you’re standing still.
What’s your dream? Does it scare you? Does it thrill you? Then you’re probably on the right track. Pursue your passion!
