Can we add this to the required curricula for K-12 kids?
Seriously though, there's a lot more societal support for being good at things than there is for struggling at things until you become good at them.
I say this as someone who hates being bad at things. I hate it. The child within me expects to be good at things from jump and wants to move on to the next thing when I'm not. (Adult me is still mentoring inner child on this issue.)
I'd perhaps add that I'd like to see us start to embrace failure as a good thing--a crucial part of the learning process.
Just as we need to encourage kids (and adults) to struggle, we should celebrate the insights and opportunities that come from failure.
