Language learning - I've been interested in languages for my whole life but I was usually too lazy or pessimistic to get into it. About six months ago I started learning French and I wish I had started sooner. Reading - I was a voracious reader in elementary school but then depression happened and I couldn't focus on books at all. In early 2014 someone from the Random Acts of Amazon subreddit gifted me Heart of Darkness and I felt obligated to read it. So I forced myself through it (I also forced myself to understand it), and the feeling of victory I got when I finally finished it led me to start another book. Now I'm an avid reader again. It was kind of an odd approach though, and I wouldn't recommend Heart of Darkness as an introduction to books :P
