Sounds stupid but it felt powerful, all the possibilities what I could become.
Some methods that seem to work, for me at least, are: meditation, immersing yourself in a particular work of fiction (especially a sci-fi movie at the cinema), turning off your phone and Internet connection, and getting lost in a new city.
Also, a hard run where you let it all go.
What's your experience with shrooms?
Look up "Academy of ideas" channel on YouTube, it has a video on this topic. I found it very interesting.
However, only for you, I messed up learning a lot of things this year. A lot. But not mastered any of it. Learn some of them for fun, some for getting employed as an undergrad, some from peer pressure. Now I can't move back to start those things from where I left.
In other words, to start over we just need to learn and keep going. Have a great journey!
Its difficult to learn anything after a large gap. As you are not a beginner yourself now. Your Baggage adds up to your fatigue.
I personally like moving to facilitate as well, changing the environment makes it easier to reframe, but does not on its own.
