One habit that has somewhat helped me is free-writing. Not for the sake of creating art, but for the sake of just expressing myself. I've been very lethargic for the last couple of years or so - I find it very hard to write things (that aren't HN comments), and my mind gives me a lot of resistance. But setting a timer to 10 minutes, playing ambient noise on headphones, then forcing myself to write down anything that comes to my mind helps me "open up" in a way. There's no "wrong thing" to write - just write whatever your mind wants to write, repeat words, write nonsense, animal onomatopoeias - anything goes, as long as the words flow. Touch typing helps a lot.<p>I feel like I'm very "closed" by default, in terms of my relationship with the world - I see, hear and feel things, but they feel dull, I can't really <i>feel</i> them. I can comprehend them, but it just feels empty, as if the whole world is fake - I listen to music, but it doesn't move me at all; I eat food, but I do it as quickly as possible to finish with the hassle; I watch a TV show but I need to put effort into not turning it off... After a quick session of free-writing, I find it easier to feel. Perhaps it's like a meditation of sorts.
