Right? I don't feel that confidence should be something especially easy to come by. Some people should not be confident with at least some parts of themselves, that level of discomfort with how you are is what urges you to change. If you are absolutely fine with yourself all the time despite glaringly obvious flaws then what hope do you have to improve yourself at all? All these people demanding the world accept their self-inflicted failures just don't want to face the difficulty of changing themselves that begins with accepting their faults.
