Back up your files so back up your guitar
Do you have an emergency guitar on hand? If not, why not? Don't you have an extra pair of shoes? A spare tire? Do you have spare guitar picks? Strings? Why not a spare guitar in case of emergency? You may want to think about it. Taking a second guitar to a gig is not just a good idea but a necessity in most cases. Think about having your most prized tool-duplicated for emergency purposes. It's great to have a spare!
