In 52 and financially could go comfortably at 55.
All my working life I've been driven, ambitious, conscientious, always looking to prove myself with one eye on the next job and enjoying a sense of achievement.
Lately, I really don't care. I do just enough to not mess up too badly, but have no interest in doing anything new or exciting.
What's worse is, I'm SLT in school and of the 6 people in that group, I'd say 5 are in the same boat. For the next 3-5 years the school is going to be run by people who've lost all interest. Things still get done but there's no oomph.
What can I do to shake myself up and what can we do as a group?
