I feel this way quite a bit too. Just the whole wishing I had taken more chances, but knowing there isn't really a good excuse for it. I think there are times when people knowing the reason for something helps, but other times is a fruitless endeavor. It's cool that the little one is so fearless!
Illness is a good example of this. It helps to know what something is, as it helps accept. But these days, I feel many are making up their illnesses as an excuse. Everyone wants that label.
Yes, that does seem to be the case!
