I’ll be up front, I am not a fan of Nike (for multiple reasons). However, as this quote from a devotional I read from John C. Maxwell implicitly notes, their “Just do it” tag line is wise:
The trick to acting on your goals is getting started. President Franklin D. Roosevelt remarked, “It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.” That’s good advice. You don’t have to be perfect; you only need to make progress. Or as the Chinese proverb asserts, “Be not afraid of going slowly; be only afraid of standing still.”
