<<the daily challenge that I crave>>
Not wholly sure that this should be your primary concern and I hope you didn't apply to join ATC simply for that. If you get posted somewhere quiet you're going to be disappointed!! My first SATCO, back in 1966 said "Bren, remember this - once you're validated and got some experience it's money for old rope". Nothing that happened in the subsequent 36 year up to the time I retired caused me to question that statement (although I guess many on here may).
