Pay attention to the work you want to do and everything'll work out fine. If you're in it for the ego, you might be successful but at a limited level.
The cruelty of nature is you have to work out harder when you get older ... It should be the other way around: Work out hard when you're a kid you should be able to coast when you get older. But unfortunately you have to do more to stay in the same position.
I still work out on a daily basis.
