While you invent， don't select. While you sketch， don't inspect. While you write the first draft， don't reflect.
Don‘t purchase extra insurance if you are renting a car with a credit card.
Habit is far more dependable than inspiration. Make progress by making habits. Don‘t focus on getting into shape. Focus on becoming the kind of person who never misses a workout.
Don‘t wait in line to eat something famous. It is rarely worth the wait.
Keep all your things visible in a hotel room， not in drawers， and all gathered into one spot. That way you’ll never leave anything behind. If you need to have something like a charger off to the side， place a couple of other large items next to it， because you are less likely to leave 3 items behind than just one.
Never ask a woman if she is pregnant. Let her tell you if she is.
Productivity is often a distraction. Don’t aim for better ways to get through your tasks as quickly as possible， rather aim for better tasks that you never want to stop doing.
Whenever there is an argument between two sides， find the third side.
Don‘t keep making the same mistakes； try to make new mistakes.
