OK. A question that's been on my mind for quite a long time now: Are we all born with different energy levels?

I'd say this question arose from its latency about the time I went to Pomona. After the first semester of college adrenaline wore off, I found myself taking naps, procrastinating, and just generally feeling tired. But then I began to notice that there were these people, and they just don't stop. I mean it's not just that they'd pull all nighters, but they'd be happy the next day too. There was even this one girl (and I have noticed without any real statistic data keeping that the majority of the supercharged people have been female) who stayed up 72 hours straight and smiled the whole time!

So what is it?

I find it interesting that these Energizer Bunnies seem more prevalent amongst the college students than they did in high school. Is this one of those correlations of success along with IQ, economic status, and all that other stuff? It'd make sense, right?

But more importantly how do they do it? If I'm tired, I can't work, I can't think, I'm useless, I'm unhappy, etc. Are they simply just better at putting their fatigue in the backs of their minds? Or have they trained their minds to be stronger? Or were they born with it?

And were those great people, those people we all like to look up to for their accomplishments, amazing thoughts, and contributions to society, did they have an endless supply of spinach too?
