It is only in your mind that you have to excel, at anything or everything. Of course, it would be very nice to excel at most things. Indeed, we recommend that you try and do your best. But realistically, you are entitled to do the bare minimum to get by. All your accomplishments are just a bonus, something to enjoy, not requirements. You don't have to do anything to prove that you are worthy of existing.
