What are your goals? Where do you want to go? How do you get there?
The most important part of reaching a goal is what you do on a daily basis, and how you improve each day. Comparing yourself to others and where they are is not the way to reach YOUR goals. Your goals must be just that, your goals, not what you envy in others, not what society says they should be, but, what YOU want.
Compare yourself to the yourself of yesterday. Grow toward your goal.
