I would like to second "learn something new each *" (for anybody, university degree or not!). It is great if you can do so on your own. If you have a hard time, you can change your situation (pay money to take courses, work through free courses online, get a mentor, study with others, work on open source projects, etc., etc.) in order to get yourself to do the necessary work to learn [relevant] new things regularly. Note that the key is yourself, not external factors: you simply have to do the work.
