Mine - Its not that great but whatever - I taught myself a language through song translation.
I was heavily into German Rock music while I was in highschool, and I would translate the non-English songs for fun, with google. By graduation, I was almost able to speak the language. Not fluently, but I got by from the people I knew who actively spoke the language.
Its been 6 years and Im not even interested in the music anymore, maybe from constant repetition of the same 4 albums over and over.
Anyway, Whats yours?
So if you already do that you can apply it to other situations in your life. Like if you get angry at things at don't want to. You can unlearn that behavior. For years I thought my self was my mind but it's just one part of the whole.
I've even gained some control of my dreams, although it's almost always reactive. For example if have a nightmare I can turn it around once I become aware of myself as a participant. I have very few nightmares, like a couple each year now, where once I had one every couple of days. Many of those were about huge, hairy spiders which are pretty common around here. Last year I had one get on my hand in real life and was able to let it sit there before gently sitting it down on the ground.
