It is funny that I have been thinking about this a lot lately too. In fact, my latest blog post deals with this question a bit. I used to think that one should first make millions. Then retire and then work on fun projects. I used to work on side projects that can generate income like freelancing or become business like social networks. Initially, these projects would be fun. I would essentially work on my side projects during any free time. Then I would get burned and take a break from side projects. And soon I would start all over again. Now my goals are to work on side projects that really interest me, with or without money part. So I am writing, reading non-technical books, reading up on Big Data, AI, and my new hobby, playing with Arduino.
