It's an alright post to me.
I actually wish there weren't limits. Actually, many people who accomplish something, and particularly if they accomplish something HUGE, say, win an Olympic event, they're pretty satisfied with it (Michael Phelps for example).
I know I don't focus on them, but they're there.
I'm not sure if this outlook can be considered scientific, but it's rational.
Because we realize we can't become the size of cars or run a mile in one minute simply by taking flying hops around the track, nor will anyone do those things.
