Agree with so much of this.
I can remember the exact moment of my own 'why even bother' moment - when City bought Stones and I thought to myself: what's the point, when there are any number of clubs like that who can just pick off our brightest and best, meaning we'll be forever stuck where we are.
Without wanting to sound too 'self-help', I think it's about learning how to continue enjoying the good moments to the max (Branthwaite's equaliser vs Spurs had me punching the air like an absolute madman), while also learning how to get over the bad moments easily - 10 years ago, Everton losing would ruin my whole weekend. Whereas that 3-0 loss to Wolves the other week when we were absolutely abysmal - 90 mins of frustration, but after that, shrugged it off and just got on with my day...
Also agreed with the point about the Man City fans. Do you really get that special feeling every time, once you start winning silverware so regularly? Does winning their bazillionth league cup really give them as much of a rush as we got when Doucoure scored against Bournemouth final game of last season? Not saying that I don't want to see Everton win things, but I genuinely think winning 3 points does feel more special to us than it does to their fans.
Anyway, born not manufactured, so got to find a way to live with it innit
