Hello, I am a high school student trying to persue a career in the physical sciences but I am getting hindered by the feeling of incompetence and being stupid. What would be the most logical solution for this problem? My teachers have noticed great improvements in my cognitive abilities but for some reason I do not notice them. This is considerably annoying considering I have high standards, one day I can do maths and physics easily but the next day I can not. What can I do about this? Should I simply convience myself of not being stupid and continue learning or what? Does not seem to work when I am trying it.
