Cool down after experiencing a defeat

Accept defeat.
Accepting defeat or conditioning your mind that you could be defeated is important for maintaining a healthy perspective on everything.

Put your ego on hold.
Losses can sometimes be humiliating, but you always need to humble yourself, learn your lessons, and keep working hard.

Do other things that will help you gain new, creative angles on your next steps.
For example, after subpar results on a project, you could take a short break and learn to practice mindfulness to condition you to excel the next time.

Take a break and visit some of your favorite places.
You will probably return with new ideas as well as a tank of energy and determination.

Stay close to your loved ones.
Your loved ones like your parents, siblings, or partners will help revive your enthusiasm for life.
