I was always a reader and a writer, so I can't really consider those new hobbies I've picked up since getting sober. Meditating is the only new hobby I've started. I do it daily. Typically a ten minute session, sometimes more if I feel like it. It helps center me and can help lower anxiety levels. It's also improving my focus and concentration. I think it's great for a newly sober person because it seems to tap into the executive functioning area of the brain. At least, indirectly. If you can learn to stop what you're doing, get totally into the present moment, and center yourself... you can extend that momentum to making better decisions. I think it's also given me a bit more compassion for myself and others. Pretty much a win-win.
