Do not measure success by comparing your progress to others. You know what you are capable of, and what your ambitions are. There are seven billion people on the planet Earth, and seven billion unique sets of circumstances. Nobody can understand your situation, except for you. Achieve success in your own eyes. Focus on satisfying your own expectations and disregard the expectations others set for you. You know what you are capable of, and you alone define what it means for you to be successful. The greatest disappointment you will experience in life is when you disappoint yourself.
