For me, it is the writing time where I feel the sense of flow these days, but I used to get it from drawing with a pencil back in the day. I don't think I have ever finished a drawing in my life though - "unfinished" is my style.
If I had more time and money, I would experiment more with materials. I have always wanted to try oils.
Writing, too actually, does calm me down, but I haven't gone deeply inside yet.
Dang! oils are pretty intimidating to me. lol!
