1914 translation by H. Rackham

"On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammelled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided. But in certain circumstances and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted. The wise man therefore always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains."

You can also invert this principle and prime the environment to make bad behaviors difficult.

If you find yourself watching too much television, for example, then unplug it after each use. Only plug it back in if you can say out loud the name of the show you want to watch. (Which prevents you from turning on Netflix and “just finding something” to watch.) This setup creates just enough friction to prevent mindless viewing.

If that doesn’t do it, you can take it a step further. Unplug the television and take the batteries out of the remote after each use, so it takes an extra ten seconds to turn it back on. And if you’re really hard-core, move the television out of the living room and into a closet after each use. You can be sure you’ll only take it out when you really want to watch something. The greater the friction, the less likely the habit.

Whenever possible, I leave my phone in a different room until lunch. When it’s right next to me, I’ll check it all morning for no reason at all. But when it is in another room, I rarely think about it. And the friction is high enough that I won’t go get it without a reason. As a result, I get three to four hours each morning when I can work without interruption.

If sticking your phone in another room doesn’t seem like enough, tell a friend or family member to hide it from you for a few hours. Ask a coworker to keep it at their desk in the morning and give it back to you at lunch.

It is remarkable how little friction is required to prevent bad behavior. When I hide beer in the back of the fridge where I can’t see it, I drink less. When I delete social media apps from my phone, it can be weeks before I download them again and log in.

These tricks are unlikely to curb a true addiction, but for many of us, a little bit of friction can be the difference between sticking with a good habit or sliding into a bad one. Imagine the cumulative impact of making dozens of these changes and living in an environment designed to make the good behaviors easier and the bad behaviors harder.
