I can't add a lot to what's already been written.

I'll just say this.... If you want to try it, then DO it. "There's always the next Games" will get you watching the lads at the next Games, and the next Games and the next Games.

Being all worried about whether you're big enough or strong enough or fast enough or experienced enough is a waste of energy. You ARE all of those things, because you're out there to do your best, not beat a whole bunch of other guys who are your mates.

maybe someday, in a couple of years when you hit the upper level of the A athletes, and trying to break into the Pro's, THEN you worry about beating the other guys. For now, get out and throw, have a freaking great old time, and give back to the sport when you can.
