Ironically, by putting in less effort at work. I know this sounds awful and a lot of PMs would probably gasp at hearing this, but I started to exert myself less at work -- worried less about code reviews, stopped stressing over small mistakes, accepted that I'm not producing the highest quality code, stopped trying to go the 110% to impress my peers and higher-ups. Really, I stopped caring as much. Choosing software engineering as your profession carries with it the high probability that it will ruin your hobby of programming. I found that I was able to refocus most of that energy to when I'm off work and can actually get my creative juices flowing on projects I care about and have control over.
