Kids go through changes in how they perceive their engagement with activities. At a very young age, they have little self-consciousness and will happily spend lots of time engaging with things they cannot do well. As they get older, frustration sets in sometimes when they cannot do something perfectly the first time they try it. I think some of the music programs, like Suzuki, try to take advantage of this by getting kids up-to-speed on the violin (or whatever) before they enter the phase where frustration dulls their interest. No parent really wants their kid to enter the cycle of repeatedly trying and quitting activities because of frustration. It eventually leads to a sort of apathy and lack of willingness to engage with things they perceive might be frustrating. This is a hard line to walk sometimes. I guess I'm just saying that you sometimes need to "push" them to remain engaged so that they can work past the frustration. It is a skill to learn that you have the ability to overcome the difficult initial learning curve of a lot of activities, sports, etc. If you can help imbue them with that skill, it can lead them to have a love for learning -- or a least not a fear of trying new things, which ultimately is the skill that can enable them to "flourish broadly," in my opinion.
