The first principle is that you must not fool yourself and you are the easiest person to fool. – Richard Feynman

Richard Feynman was an American theoretical physicist, known for his work in Quantum Mechanics, Quantum Electrodynamics, Path Integral Formulation, particle physics and many more areas. For his work he was awarded the Nobel Prize in Physics in 1965. When people asked him about how he could be able to tackle such a diverse range of problems, he answered that he had a list of his twelve favorite problems. He would think about them all the time, and when he had a new idea, he would check if it could be applied to one of his twelve favorite problems. If it could, he would work on it. If not, he would discard it.

The famous and prolific novelist Ernest Hemingway came up with a mechanism to avoid writer's block. When he was about to finish a writing session, he would leave some room to write down his next steps, noting the point where he had left off, his major obstacles or difficulties in wrapping up a plot, or the most important open question to be resolved.
