I will say that I do think that time was only really created to keep us in check. "Be here by then, there by this time, then over here by then!"

We've built our world up around us to serve order, so, obviously, we needed something to make sure that things got done when we wanted them to be. Thus, time.

I really don't think that early cultures had such a strict tie to time. I think in our world, we only make ourselves more miserable because we're such slaves to time. Constantly we are bombarded with the fact that we are ALWAYS on the clock. Sometimes we have to give up sleep because of TIME. Sometimes, we have to do things in a way that is not up to par in terms of quality, because of time. We have to rush rush rush, until our lives are nothing BUT.

Time IS a knife, but like any other kind of knife, it's been in our backs since the day we were born and there is no real way we'll ever be able to get it out.
