The gradual decline of a society is often a self-induced process of trying to meet ever-expanding appetites, rather than a physical inability to produce past levels of food and fuel, or to maintain adequate defense.
The part you don't expect when you start out is all the people who come into your life wanting a piece of you, not caring about your wellbeing. The insane schedule is very difficult. Touring looks very glamourous but it's hard and gruelling - the travelling, the meet-and-greets - it was too crazy.
