Somehow my whole life I have been able to commit most of my spare time to projects like this (I even built two hexapods like this in high school, over 20 years ago). I do hear what you say often from other people. All I can say is that finding a way to get yourself to do it can be very rewarding. I have so many projects I am proud of, and learning to make new things has helped me jump career paths multiple times - I now have my dream job. Find some way to do it! Its super fun.
