My first assistant-coaching job in football was at William & Mary in 1961. The pay wasn't much, so to get $300 more per year, I agreed to coach the golf team. I didn't even know how to keep score, and really, my main job was not to wreck the van on the way to tournaments.
Sacrifice, discipline and prayer are essential. We gain strength through God's word. We receive grace from the sacrament. And when we fumble due to sin - and it's gonna happen - confession puts us back on the field.
No matter how bad someone has it, there are others who have it worse. Remembering that makes life a lot easier and allows you to take pleasure in the blessings you have been given.
Remember this. Bear Bryant retired at age 69, and he died 28 days after he stopped coaching. If you don't have something, and a purpose in your life, you're gonna die.
