All bets are off, all debts wiped clean. You get to start over. You no longer have to carry the burden of inherited rules and expectations. You get to go crazy and live that dream, start that business, take that trip, learn that course, explore that alternate lifestyle, and write that book.
The precursor to enthusiasm is giving a damn. Find something that you deeply care about, and work from there. For example, are you self-conscious? So you care if you end up looking like a fool? Excellent play to that, tell yourself I NEED to do this and if it fails, I’ll look like an idiot. I NEED this to work. I’m giving it my 100 percent because failure is just not an option.
