An agent won't help you get drafted higher, won't make you win more games, and won't make you faster or stronger. They all say they can, but the people who do the drafting don't talk to agents. They talk to coaches, they watch film, they talk to the people who've worked with players. They don't talk to agents.
Do what's right! Do the best you can and treat others the way you want to be treated because they will ask three questions: (1) Can I trust you? (2) Are you committed? (3) Do you care about me as a person?
I'd say handling people is the most important thing you can do as a coach. I've found every time I've gotten into trouble with a player, it's because I wasn't talking to him enough.
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.
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.
