She may not have been a great engineer (I'll never know), but she gave us the tools we needed to do our job, shielded us from the upper management pressure and BS and got out of our way. In return, the team shipped a ton of functionality in an impossibly short timeframe that she later confessed she never thought we'd be able to achieve.
Excel at what you're good at and the rest tends to take care of itself.
One of my bigger challenges is that the older I get, the more I care about people and want to work on those issues... which means I gradually lose interest in code and pure technical stuff. The longer I stay stuck on the IC track, the more obvious this is going to become.
