Some things I would tell my younger self: You are extremely sensitive to caffeine and should not consume coffee, tea, or even chocolate. You don’t have an attention problem. Rather, you sense danger everywhere and can’t relax enough to focus. It is far more pleasant to choose beliefs and thoughts for their practical utility than for their correctness. This is a change of axioms and not something that can be reached through reasoning.
