I actually reached the same conclusion as you after playing a lot of League of Legends. Why do I play that game instead of working on my projects? Because of all the reasons you mentioned, but most importantly because I am good at it and feel like I progress by getting better with each match. There's also the satisfaction of winning, especially when the odds seems against you.

I am also trying to find the same feelings while working, but getting the same rewards takes a lot more time than while gaming. Also, it's a lot easier to feel that you are bad at it or that you are not learning as much, or that maybe you are working on the wrong thing when programming than when gaming.

Also, I am really missing a real-life leaderboard. I am pretty competitive and seeing others that are way better than me motivates myself to work hard in order to get to their level. I am always looking for success stories and seeing actual numbers from great projects. I found that IndieHackers is a good place to find motivation from others' work.
