My best guitar is the best because it sounds great, plays beautifully easily and consequently gets played the most. It also inspires me musically so why on earth would I want to to do myself, it and an audience a disservice by not using it as it was intended?

Give your guitar reasonable care and, if you're gigging with it, keep it in a case whenever it's not being played, e.g between sets. It's just common sense.

A guitar isn't an ornament to be polished and pampered but a musical instrument which will pick up a good collection of beauty spots during a working life. A G7th capo fell out of my shirt pocket and bounced off the top of a Martin J40 I once owned while I was bending over to put it in its case-three lovely dings. Shit, as they say, happens.
