...To be honest, if you're smart enough to skip enough grades that it would become alienating in your mind then chances are that it was already alienating before you did it. Imagine having the knowledge you know now and being put in an 8th grade class with a bunch of middle school students. Not only would the classes be so far beneath you and boring that it'd be all you could do to stay awake, that is if you don't just straight up sleep through every class and still pass with a perfect grade, but it'd seem like everyone around you was mentally deficient.
To be honest, it really depends what you want out of life. For most people I'd recommend to enjoy their childhood as long as they can because adult life sucks. Bills... responsibility.. pah. But, skipping ahead is better for some. It also gives you way more opportunities. Everyone likes young people. If you go through everything so fast at the top of your class that it's pretty obvious you're a child prodigy then do you really think that someone that just went through the motions, even if they did it really well, will ever be picked over you? You're always everyone's first choice, pretty much anywhere you want to go. It's not because of your profession and your degree, it's because you've just proven to the world on paper that you're a motherfucking genius.
It's called having an attendance rate of about 50 percent and having some 100 hours a week to spend on ones hobbies. To be honest, I quite liked that, in comparison to the current <<20 that I have now.
I disagree. I know a fair amount of geniuses that didn't do shit with their life due to depression or some other factor. By the time you have some experience under your belt, recommendations and relations do far more than "Was a Valedictorian". And protip, being an arrogant prick doesn't help with the former.
