“Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn’t matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough. Work as hard and as much as you want to on the things you like to do the best. Don’t think about what you want to be, but what you want to do. Keep up some kind of a minimum with other things so that society doesn’t stop you from doing anything at all.”
I have always liked solving problems. Diving deep into any problem teaches something and learning is fun. I find interest in problems involving both Theory and Computation, it requires one to build a better understanding of the theoretical concepts and tools. Also having a requirement and opportunity to connect to diverse community of people is fun.

Photogrammetry has been a recent budding interest. The subreddit ( /photogrammetry ) is a good place to give one a look into what different things it can be about.
