Don't focus on letting go, instead focus on what you want to let into your life. Focus on the exciting feelings, relationships or habits that will improve your life.

Avoid all-or-nothing thinking. Don't use terms like never, always, nothing, or every. Change your thoughts by looking for an alternative, a grey area.

Talk to yourself differently. Ask yourself: "How would my best friend or parent support me and help me in this situation?".

Give yourself credit for the small things. Even if you are not done with a project, take a moment to focus on what you've achieved so far.

Get grateful. Take a minute to think of everything in this moment that you're really grateful for.

Improve the moment. Do something that interrupts the negative thoughts (call a friend, listen to a funny podvast or turn up the music).
