Well... no matter when you change your strings set... is good... professionals that play EVERYDAY usually change them once every week or two (E,B and G) for best performance in general at home use I would say like once every 2 months or 3... but well... this isn't a rule... because of the sweat of your hands etc... they lose the brightness of their sound.... don't wait to get mug on them or whatever to change them... every two or three months is a good time to change them..... if this seems too early for you just think that guitar strings do not cost so much anyway...
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
