Many times when people ask what to build or work on (much like the author) are told to focus on things they need - Scratch your own itch! Lately I haven't really found many things to focus on working on due to this. I highly doubt I can think of many things in my life that would be close to a "stand up comedy routine".

I mostly just want to figure out something I can work on in my spare time to learn outside of work. It doesn't have to be a business (although I wouldn't be upset if it eventually turned into that), but even having a userbase would be a fun experience.
