You can compare yourself to others to some extent as part of a [life long] learning process but make it productive: don't go too far and extract a few key points that are viable for your own improvement at this point in time and apply them. Do it again. You have lots of time at 23. You don't have to start coding at age five to be a descent software engineer, but it will take a few years, possibly a decade. Who knows, maybe the next Carmack started later too.
