While this article focuses on physical gains, its very applicable to trading too.
Even though I have like freaking 15 winning trades in a row I’ve become frustrated with my results this year. This type of research makes me feel better, I firmly believe that if you just keep grinding out walks and singles, sooner or later some doubles and homers will follow.
In the beginning, there is basically no difference between making a choice that is 1% better or 1% worse. (In other words, it won’t impact you very much today.) But as time goes on, these small improvements or declines compound and you suddenly find a very big gap between people who make slightly better decisions on a daily basis and those who don’t. This is why small choices (“I’ll take a burger and fries”) don’t make much of a difference at the time, but add up over the long-term.
On a related note, this is why I love setting a schedule for important things, planning for failure, and using the “never miss twice” rule. I know that it’s not a big deal if I make a mistake or slip up on a habit every now and then. It’s the compound effect of never getting back on track that causes problems. By setting a schedule to never miss twice, you can prevent simple errors from snowballing out of control.
