The document discusses various learning techniques:
1. The Pomodoro technique uses intervals of focus and reward to fight procrastination.
2. Focused and diffuse thinking can help solve problems by focusing intensely and then letting the subconscious work in the background.

4. Meaningful associations link new information to concepts someone already understands to improve recall.
