Relearning to Learn
Having a goal, and creating an environment where you can frictionlessly work towards it for a little bit of time most days, is such an unreasonably effective tool. You'll never become a true, deep expert in something with 10 or 15 minutes a day, but in my experience that's all it takes to become perfectly capable at a lot of things.<p>A few years ago I started having an hour most days that I devote to learning and trying new hobbies / habits / whatever, and when I find something interesting I start giving it a 20 minutes slot in that hour until I stop liking it or I feel I've gotten what I want to out of it. I'm nowhere near a professional at any of this stuff but I have a fulfilling level of competence in a ton of interesting things now, and it's brought me a lot of pleasure.
