29. Choose short-term pain for long-term gains. For example, reading, exercising, and having heated discussions with intelligent people who hold different views, listening to perspectives you might not initially agree with.  
30. Deliberately analyze your subconscious. For instance, if you bought Bigtime last night purely on instinct, unsure whether it would make or lose money, after selling it the next day, you must carefully analyze what your subconscious was thinking. Even before buying, you should analyze your subconscious.
