Simple idea: if you’re stressed or you’re really sad, it is good to know what makes you laugh. Laughing is good for your health and it lowers your stress levels, to name a few.
If you know what makes you laugh, you can easily return to this when you need some positivity. It can be a specific part of a movie you know cranks you up. It can be a section of a great book. It can be my go to gif. Make sure it is something where there is a high chance of you laughing out loud.
