> I think that almost everyone should be able to achieve a solid 2000 elo rating, with enough dedication over the years

I went to check rating to prove how unlikely this is. Sure enough, that would put you just outside the top 100 players in Australia.

But then I noticed the guy who played one board above me at school when we played is rated above 2000, and he wasn't really much better than me.

So yeah maybe it is possible!
