Is there something that you’ve always felt you were naturally good at? Think about that “talent” and try to remember all of the practice that you actually did to get good at that thing without realizing it.
Naturally fit? Maybe you grew up in an environment where you loved running around and climbing trees a lot – you were practicing without realizing it.
Naturally good at cooking? Maybe you’ve spent years putting together meals from your cabinets and learning what goes with what – again, practicing.
“I’m not naturally good at that” is really just a wrongheaded way of describing something that you haven’t practiced enough. If you find a fun way of practicing something without realizing it, then you will eventually become a “natural” at it.
