as far as tanking...the first Sweepstakes I got in C/SR with a high school group was the semester I had ZERO outside of school rehearsals. It was when my daughter was born and i just didn't want to work late. I planned my rehearsals better, and stayed focused.
It's not perfect, but I work late Mondays and Fridays (during football) and the other days I got home before 5:00. I also try to schedule kid/wife time during the week as well.
