1. Read Why Fish Don't Exist, and don't read anything about the book before starting it.
2. Play Baba Is You. It's available for major computing platforms, smart mobile devices, and Nintendo Switch. If you get stuck, don't cheat! That ruins the whole point of the game. Instead, check out guiding hint sites like Baba Is Hint which help you think about how the game works instead of giving away the solution.
3. Get a therapist or counselor even if you don't think you need one. Really. If there's nothing "bad" or "painful" to talk about, you might still learn about yourself and learn to think about your own thoughts differently with a therapist's help. If things are already bad, it totally sucks to jump through all the hoops and forms and insurance and such to get connected with a therapist. Get started with therapy before your energy state is super low from grief, trauma, depression, anxiety, whatever. Future you will thank you.
4. Eat Joe Chips. Serious but non-damaging crunch with just the right amount of give, excellent flavor dusting. Try out the assorted chips linked, and learn what your favorite flavor is. The BBQ flavor of Joe Chips (BBQ is generally my favorite chip flavor) has just the perfect balance of salt, smoke, spice, and sugar. I have not encountered anything else out there so balanced. BBQ chips are often too smoky (I usually pass up "mesquite" labeling) or not sweet enough. Not BBQ Joe Chips.
5. Go on a walk through a forest or park, and try to find one object of each color of the rainbow. Maybe you'll find a red leaf or an orange peel, or even a yellow dandelion. Make a note of your discoveries somewhere, or even take photos of each object of each color and arrange them to form your own lovely ROYGBIV. This exercise was adapted from Why Fish Don't Exist, but it doesn't spoil anything, I promise.
