I agree with you in terms of there are bell curves for innate athletic ability etc etc. but for the vast majority I would say that if it takes you more than a season to stand up on a surfboard or parallel ski then there is probably a fundamental blocker somewhere up the chain. Either a mental block or an area of training deficiency that can be much better remedied with a focused effort in that area. In these cases I feel trying to do a complex, nuanced, full body sport is akin to doing Calculus without grasping Algebra. You can take that Calc I class 100x and you will still fail. I am not trying to be critical of those who struggle to learn but suggest that there is often a way to shortcut that frustration. I love seeing people "get" a new sport and despite how inspiring their persistence it is really disheartening to see people fail unnecessarily for years.
