You can even use your imagination to keep unwanted thoughts away.

Every time that unwanted thought occupies your mind, consciously think about something pleasant instead.

When people are stressed, they tend to fall back on ingrained habits - regardless if they are helpful or harmful.
Start responding to mild stressors with better choices. The more you strengthen your habits, the more likely they will be there to rescue you when a major stressor comes along.

People give up because they feel overwhelmed by the enormity of the goal they must accomplish.

Break the goal down into manageable pieces and line them up in a sequence that guarantees that you will never put yourself in a state of willpower depletion.

It takes an immense amount of effort to suppress your normal personality, preferences, and behaviors.

Hold true to your own internal goals and desires.

People with high willpower use it to avoid getting themselves into a crisis.

If you can’t prevent temptation, make a plan in advance for what you are going to do instead of succumbing.
