My wife me a better programmer and yet better person. She is HR (in the ICT area) and we are together for 12 years. She was always joking me that I am mediocre or average when I was actually at this level. However, this was a constant powerful reminder to become better, so eventually, I did. Everyone - find your motivation to be better.
