My good friend constantly complains about that very same thing to me, and honestly, it's starting to grate. Why is it an expectation that a child would have a passion and excel at it? Why can't kids be respected for being reasonably good at many things, even if they're not publicly recognized for it? If your child feels low-self-esteem and a lack of an extra oomph, he just needs time to come to terms with himself, which is normal. 11 year olds can't be expected to find a sense of self easily.
You have to keep on encouraging him and one day, he will understand that he is much better at certain things than others, and that he doesn't need to win.
My child is gifted and also has disabilities. There hasn't been one thing in his life he is average at, because he's either failing or way beyond grade level. That comes with enormous confusion and often conflict and misunderstandings for everybody, including him, and it's not easy to manage. My point is, we should all be grateful for what we have, and the grass isn't always greener.
I totally agree. Two of my kids (boys) are just like the PPs, except they're not gifted. We aspire to average. We've worked really hard with them (and spent a lot of money on therapies) to help them identify what they like to do and develop their skills. They're never going to be great at these things (again, we aspire to 'average). But, document their progress, see how much they've improved. talk about doing things because we enjoy them and doing your best. If you haven't already, I suggest you read Carol Dweck's work on "Mindset".
