"Look at that runner! No way I'm ever going to catch up! I'm not even close. But hey, look how far ahead I am of the runner at the back of the pack." Comparing with others breeds pride and inferiority, and is a distraction from our game plan. Just run.
Looking sideways or behind isn't the best strategy in running your race. Sure, learn from and be motivated by others, but avoid the trap of evaluating your worth by comparing with others. Your most difficult challenges will be with yourself, so don't be worrying about the next guy's strengths and weaknesses. We've got enough stress as it is. Run well in your own lane. Be consistent and diligent. Put on blinders and just go.
