I struggle with this. Whenever I'm trying to do something, and generally being a bit shit at it, I have no way of honestly assessing if I'm trying 100% my best or not.
There is always, always a voice pointing out I should be trying harder, pushing more, berating and scoffing for my shit efforts. I think it is because I am so mediocre at everything, I never see results that sort of show me my efforts are respectable? It's difficult to explain.
How do you know you're doing your very best? How do you recognise what that is?
