Can you be weaker than yourself?
I do things that I'm really good at while other time I'm barely holding my own. Like for example sports; sometimes I'm really good at it, I do things that few people around me can do and things that I didn't even know I was capable of. And some other time in the exact same area, I can barely do the minimum while not being especially tired.
Does it happens to you in some areas too? Or am I the only one being this inconsistent? Am I normal?
