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.
What you are capable of achieving is determined by your talent and ability. What you attempt to do is determined by your motivation. How well you do something is determined by your attitude.
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.

I follow three rules: Do the right thing, do the best you can, and always show people you care. You’ve got to make a sincere attempt to have the right goals to begin with, then go after them with appropriate effort, and remember that you can’t really achieve anything great without the help of others.
