Yes, a few:<p>In late 2017 and early 2018, I started to learn sleight-of-hand card magic and am now able to perform a number of illusions and flourishes. I'm not particularly great at it, but its enough to entertain most people a little.<p>Last summer, I started to learn guitar. Again, I'm not great at it, but I can play a few things and can pick up new riffs quickly enough (as long as they're not too hard to begin with) and, most importantly, I can play for fun and relaxation.<p>Two months ago, I started going to the gym almost daily.<p>In all cases, I set myself about an hour each day to do it. I kept a little calendar where I'd tick off each day as I practice. This was done to make it part of my day to day routine and to get over the initial "hump" where learning is slow. After one to two months, I wouldn't bother with a calendar and just do it as I feel like it (its hobbies after all), but I did make sure it was always easy to do: I always have a deck of cards within arms reach, I have the guitar on a stand beside my desk, I go to a gym that's 5 minutes walk away. Convenience is key, for me.<p>For guitar and cards, I also signed up to online courses (video lessons). Both have plenty of youtube tutorials, but I find that to start off, something much more structured is better for me and they're designed for beginners in mind (so will start with the fundamentals). Nowadays, I just go by youtube tutorials when I feel like trying to add to what I know.<p>For me, I chose those things because they are completely unrelated to my work (programming), interesting to me and in the case of gym, would benefit my health.
