I was able to curb my nervous/bored eating and drinking with bitters and sours. Instead of reaching for food I now reach for some tea (with just lemon), coffee (decaf black), a glass of water with lemon, or just suck on a lime wedge. The lime thing is mostly to curb alcohol cravings.
PS: My wife’s answer was Kombucha. Everybody is different.
I can start it now but it won’t get finished and it won’t get done right. I don’t think the same unless I’m under pressure. Pressure breeds perfection.
I don’t know about visual art but there is about music. Exposing a baby to complex music (many notes), like classical and jazz can help develop perfect pitch. The brain learns musical notes like it learns language.
In my sophomore year at college I needed to add a “filler” class to have something to do in campus between my two “real” classes. I chose to take Logic and it was one of the best decisions I ever made. Not only was it interesting, it helped me think and analyze arguments. I am pretty sure there are universities that give you free access to the course but it wouldn’t surprise me if you can find logic courses for free on YouTube as well.
