Mentoring young people whether it's hunting , fishing , work , ect can bring back a lot of the satisfaction. Seeing the world anew through their eyes will help bring back some of the magic. Hunt something new or a different style of fishing. Connect with some guys from here or local bike club and schedule things so you have to go. I'm only 45 and I'm reinventing the way I hunt this year. I was hunting whitetails locally but this year I ditched the club and got a backpack and tent and I'm off to hunt elk. I may not kill anything and freeze but it will not be the same old thing again.
