I think I am happy in that regard, because I do the best I can with the resources I have decided to allot, and let go of the rest.
You may be dissatisfied because I detect a hint of the horrible monster Comparison in your thoughts.
There will always be others more "this" or less "that". Can't compete with them all, better to make them your friends, if you can.

Also, to repeat a cliché, we are always our own worst critics. And those you percieve as achieving more very likely don't see themselves that way at all.
Are you certain it's a constant message of "Be perfect" others are sending...or is that just what you are hearing?
