Desire for oblivion often masquerades as humility. But it's just another form of giving up. Using the 'I'm not good enough' excuse to not do things can feel like you are being 'humble' and lacking in self-centredness. But doing things, even if they aren't wildly 'successful', is more positive and has more developmental possibilities. If you've got a donkey why not ride it? No one gets anywhere just looking at their donkey and seeing all its faults.
