Where did you find the time for this? That's 14 hrs per day with a two day weekend or 11 hours over seven days.
The 5 day week is 8am to 10pm which is just insane while I could probably do seven days for maybe a month, I definitely couldn't sustain this for fifteen years.
Even when I had a full time job and a PhD to finish, I rarely went over 60 so super curious how you accomplished this.
