Hey
First of all, congrats. You sound like you're on top as far as someone can go externally. Now it's time to work on your personal, deeper aspects life.
So, from what I've read, you're always seeking challenges - and conquering them. That's great! Not nearly enough people do that.
Always bored? Find a passion; something that you can do without any reward at all. Charity? Non-profit work? Playing an instrument? Do something that fulfills you; but don't focus on the outcome, instead focus on the process. The boredoom will disappear.
PS: Don't worry, you're not the only one who's not satisfied with their life. IMHO the best example is Bruce Dickinson: Lead singer of Iron Maiden, awesome solo career, honorary pilot for British Airlines, fantastic fencer (even has his own fencing equipement company), book writer, radio host... When asked how come he's done so many things, his reply was: "I was bored, and I hate boredoom."
