This is what taught me to sublimate my own ego. Overcoming the wickedness of others with patient, meditative calm can be an incredible experience. It just takes longer than a business day to play out. You've gotta think across much grander time scales. 3 steps ahead, at minimum, at all times. Burn these people out of your team. Take charge and stay focused on the customer. It often takes non technical people a little bit longer to lock onto complex problems and downstream consequences. It's taken me nearly 2 years to deal with one bad hire. All I can fantasize about is being in a position to never hire that kind of person again. The destruction some people can cause in a business is unthinkable to those who haven't seen it yet. I didn't believe these people existed until it was way too late.

I still prefer to solve technology problems, but I see a bigger and more important mission out there. Keeping the team happy and aligned on the customer is much more rewarding overall. I'd rather 5% dev time in paradise than 95% dev time in hell.
