Sorry, this is the way I analyze things for me, but it may not work for you. My real question (to me) is do I really want to push myself indefinitely or the thing it is that I "have to"? If I have to, why is it? Do I really believe in this value despite it is destroying me? Maybe I will always hear that voice inside "you have to be/do better, you have to be/do better". But that doesn't me I have to listen to it
