Side project at work is a different thing. I do recommend them (at home), but that's irrelevant. It's irrelevant, because if coding is something you love doing, you will have many side projects and enjoy them not caring all that much about their profitability or how do they look in your CV. And if you don't, why would you want one? Do the things you love. Possibly consider changing your career (but I guess this may be tough especially if you are a good coder).
