For you folks working 12 hours or so a day. Are you really efficient working that many hours. From having my own CPA firm for almost 50 years, I found that most folks can do the long hours for a few weeks, then suddenly their production becomes 40 hours of effective production gets done in 60 hours.
Take some time to smell the roses, go fishing, go to a play, go to a concert, go camping, do some gardening, or something you enjoy that is not work related. No matter how much you enjoy what you do, we all need a "mental health holiday" every once in a while.
