HN: How can I make my brain/mind sharp again?
https://news.ycombinator.com/item?id=1469730When I was a undergrad my mind was really sharp, I was clever and great at solving programming problems. Though it now has been about a year since graduation, and while doing other non programming work my mind has gone cloudy. I know it sounds funny, but it feels like their is fog or sand up there. Even looking back at past clever solutions I made, today I don't really even understand them. It's as if there is a mental block there, as if the nerve routing goes to the right place, but the signals just cant make it.
How can I get my mind sharp again and fast? What are some good but difficult problems, which will keep me interested but also work the heck out of my mind?
