The first day back to work after a long vacation is always tough. My brain isn’t ready. I’m not ready to work on other people’s problems yet. The best part of vacation is getting to solve your own problems and pursue your own passions when they overlap with your career. I absolutely wrote code on winter break, and it was code that I needed for myself. The likely lesson here is that I need to continue to set aside time to code for myself, and not wait for vacation again. There is a pure joy that comes from writing code that isn’t for somebody else’s roadmap.
