There's a lot of value to just jumping into things. Especially learning new things where there's no risk other than learning something that you might not end up using- but will certainly help you down the road regardless of its actual utility. There has to be a peak for those who may be naturally higher intelligence, and being surpassed by those with lower natural intelligence who have a broad basis to draw on down the road from all the learning experiences they jumped on.

As for the physical stuff, I can't say you're wrong to think this way but reading that gave me a mental image of a boy in a bubble, wearing a body condom.
