Just don't be surprised that people doing code outside of work will probably get better jobs / get hired more easily.
Some people are really passionate about the field, and don't really see it as "working" I think it is important for these people to have both professional projects and personal ones.
But like a lot of people that are passionate about something, a few of them will end up being light years ahead of people just doing it for money, or seeing it as a "regular job" just like any other job.
