Apparently "grit" is one of the surest indicators of future "success" in life. Not natural ability. (Tho some natural ability/lack of physical problems will obviously help, & in some cases might be a pre-requisite.)
So, if your child can manage to stick at learning/doing something they want, (or have), to do, (however 'bad' they might be at it to start with), this (learned) "grit" might end up being a lot more useful to them (later on) than a mere high IQ or a natural 'gift'.
I also reckon that beating "yourself", (ie the desire for self-improvement) is a better measure of progress than beating "others".
Say I took part in a "5km Fun Run": I would obviously be trying to beat my own piss-poor previous time and not trying to compare myself to some marathon runner my age!
And in the world of work, effort, concentration and having long-term goals probably makes for a more valuable employee than flashes of genius, mingled with thinly-disguised boredom/lack of comitment.
I really like the fable "The Hare and the Tortoise". (Might be a good story to tell to your child, to give him/her some hope, in spite of being far behind the pack in many areas for now?)
Personally, I have seen talented people who gave up, (and under-achieved), as well as "try-hards" who slogged away and then surprised everyone by eventually becoming high achievers. So please don't despere!
Learning to come from "behind" is a really great asset for a child ... for the future. (As well as not having too much of an ego from having had things happen too easily.)
Agree that life is competitve & so it's a non-sense to say "never mind if you come last". But it's also good to know that:
a) someone always has to come last
b) taking part, (and coming last), is a lot braver than not taking part
c) coming last, (eg in the Olympic 100m final), does not necessarily mean you are bad at something
d) beating "yourself" is a better measure of progress. (As you can only do your best with what you have.)
e) slow and steady sometimes wins the (long) race!
You sound like a great mum by the way! :-)
