Exactly. If you have low expectations of yourself, you're likely going to meet them every time. And you'll be no better than everyone else with those same expectations.
But if you expect to do well, to learn and improve, and you dedicate time and effort into it, you can often exceed your initial expectations rather quickly.
I completely agree with this but I think it's unrealistic to expect that most people will be runout players in a year. I'm not saying its impossible but it would be the exception and not the rule.
