 We can remove bad habits out of our life to clear up space for the good ones. And what we do is we add friction to the bad habit. So this is like if you're eating too much junk food, put the junk food away in a cabinet that's really hard to reach, maybe above your fridge where you don't normally go. And so it is remarkable how little friction is actually required to get you to stop doing a bad habit. If you can't stop smoking cigarettes, go put the cigarettes out in a lockbox in the garage and you have to actually consciously go through the act of unlocking this box and acknowledge to yourself that you're breaking your promise not to engage in this bad habit.
