Research shows we don’t use much willpower when something is a habit.

Build new habits by manipulating your environment so as to make what you should do easy and what you shouldn’t do hard. Remove the cookies from eyesight and put your running shoes next to the bed.

Willpower is like a muscle. When you overuse it, it gets tired. But exercising it over time will make it stronger.

You want to rely on habits and exercise willpower steadily.

Improving willpower is as easy as eating and getting enough sleep.

Adults who routinely shortchange themselves on sleep have less self-control.

Postpone your temptation to gain discipline.

Tell yourself "not now, but later." It is more powerful than denying yourself something.

The reality is that you will give in to temptation. What is important is what you do after you fail.

Don't blame yourself. It reduces self-control. Showing self-compassion increases it.
