Mike,
Being over 40 myself, I KNOW how hard it is just to stay in shape. You went beyond that and got into a condition that 85% of the people on here will NEVER see themselves. You set a goal and reached it. Most here don't even know HOW TO SET A GOAL. For some their goal is just to rip others because that's WHAT THEY DO BEST.
You reached 1 goal. Now set another, make sure it's attainble and realistic and go for it! That's the great thing about life, there is ALWAYS something else to look forward to. Many forget that we are lucky here in the US compared to other countries for the oppurtunities that we have about us and that are wasted because of laziness and taking the country for granted. Not to mention most of us aren't missing legs, or hands, or arms for that matter yet don't use our potential to better ourselves one way or the other.
If you had a client reach a goal you help them set another. Do the same for yourself. Congrats again.
