2. Work out and Memorize Things
Repeating things aloud is a good way to memorize things, and even if your studies are based on research, there are things that you will still need to recite. Recite principals and tenants for each workout move you do. Every push up you do could state one of Newton’s laws, and then each subsequent push up could state his equations, etc.
You could force yourself to recite summaries of your learning principals for each move you make. For example, you could lie on your back and hold your legs up (working out your stomach muscles), and you have to leave them up as you describe the intricacies of a marketing technique. If you cannot then you have to hit the books and remind yourself before you do the same again.
