As you age, it's easy to become jaded. The problem is that the more you experience,the less there is that is new and exciting. After the 1000th Pizza, it doesn't excite you like it did when you were 5. After sex a couple thousand times-can take it or leave it. 4 cruises are probably enough. Made six figures for the last 17 years-boring[I wouldn't like to make less though]
What I still enjoy is hunting-walking alone by myself with no people and no sounds except my breathing and footsteps. The sound of the wind blowing through the grass and my sharpened senses as I return to my primitive roots. If I had to work that hard, I'd change jobs. BUT I love it. It is my passion. You need to accept that things won't be as much fun as when you were a child. BUT find your passion and live for it.
