you shouldnt look at yourself that way. no one should. being enough or not enough is a subjective manner - when you begin looking at yourself as "not good enough" nothing will be able to change your mind, except for yourself. but you wont, it will only get worse. you will start to realize more things about you that you dont like or that you could improve, and you will fall into a depression abyss from where one cant possibly go back with no external assistance. i am not saying you shouldnt wish for being better or that you shouldnt hone your skills. im saying that you should try to accept your failures. everyone does them. and thats okay
