So one of those things about getting older and having kids is you invariably end up doing things that you may not have expected to do for their benefit. For me, that's coaching basketball.
I also coach baseball. I played baseball for a decade when I was younger. I umpired for a few years. It's a game I know pretty much inside and out, and a game I have a pretty good grasp on coaching from pretty much all aspects.
Basketball, on the other hand, was a sport I did not like. Didn't like to play. Didn't like to watch. My dad always loved it, but it wasn't ever really my thing (I was also terrible at it). When my older son was in Kindergarten, he wanted to play, so we put him on a team. A team that ended up being really, really bad. At the end of that season, I said that if I could get a full team together from his school, I'd coach it. I couldn't be any worse at this, right?
Fast forward to the following fall. We got a full team. My dad volunteered to help coach (as I mentioned, he loves basketball). The season started as you expect: we lost the two games before winter break. Kids come back to school in January, and I full expect to see us barely pull a win or two out.
We won the first game back. Then the second. Then the third. All by double digit margins. That team won 7 in a row to close out the season 7-2.
This fall, we lost 2 players, and picked up two new ones. So far, the team is 5-0; 4 games left before the playoffs. I don't know that this undefeated streak will continue (we're in a tough division), and I don't know that any of the success is actually attributable to my coaching (though I give my Dad a lot of credit; he knows what he's doing).
This was a rambling way of saying:
Do things outside your comfort zone. It's good for you. And if/when you have kids, do things outside your comfort zone for them. It's just as important for them as it is for you.
