The "get them to" part is the killer. I was easily frustrated as a kid and quit a lot of things in hindsight that I wish I stuck with. You never realize that time now is an investment for later, or that learning curves are different for everyone as a kid. I think that environment where you are in a cohort as a kid can be challenging too. If you see a few people in your class who are really good at something and you are struggling, that kills your confidence, and you will probably quit before actually putting in the work you need to get yourself to that same level and just assume it will always be impossible for you. As an adult now I see a lot of my peers still with this mentality and they drop new hobbies fast. Life is a slow march though and you shouldn't hold yourself to the standards of others, but that's a lifelong lesson that even 35 year olds are learning, and not something you can easily tell a 5 year old.

Of course, if you push too hard the other way, your kid may just hate the skill and drop it. I knew a lot of people who were forced into piano lessons, and got very good at it too. Many quit over the years due to that resentment once their parents gave them the choice, and today never play any music in adulthood. Such a shame.
