Arrive early.
Set up the amp and turn it on.
Tune my guitar.
Wipe each string with my WD-40 rag.
Check quietly just to make sure everything works properly.
Check the settings on the amp.
Order a beer.
Help other musicians set up.
Wash and dry my hands so my hands are clean when I play.
Check the tuning again after it has adjusted to the room's temperature.
Ask the Lord to let me have a good time.
Play and have some fun.
