I know in the world of education and work, our performances are constantly being measured by others. This is an aspect of life that we learn to cope with when we are kids.
Ultimately however, the progress you make in your own self-development has to be measured by yourself.
It makes no sense to compare yourself to others, because there will always be someone who you perceive to be better than you.
Humans are very similar from the inside, but when it comes to displaying skills and abilities we all vary like crazy. In this sense if we are all so different, I repeat – it makes no sense to compare yourself to others.
