now I just go to work, do the job to the best of my ability, take the salary and go home.
That's exactly me today. I am fortunate that, since last year, I can retire at any time I wish, with a cap set at 65. I'm soldiering on for a few more years (but not to 65!) just for the money and no longer for the love of the work. The organisation I work for is a circus - and the clowns that run it aren't even remotely funny. The only thing that I'm thankful for is that at least I worked 85% of my ATC life in the golden years of aviation.
