I see you are an undergraduate so I presume you're young. I'm neither old nor young, so let me tell you something (I'm not being condescending, I want you to take this to heart) - you won't believe how fast it all goes past. Until you start to see it happening, you don't quite believe it. One day you're 25 and it's all in front of you. Suddenly you're 40 and you hope that you've got long enough left to do everything you wanted to before the credits roll.

The worst part is the acceleration. The older you get, the faster the days fly by.

Yeah, and once you have kids it seems to get even worse... on the plus side, not having to wonder "am I doing anything really meaningful with my life?" any more is a bonus. On the other hand, you're forced to face more mortality; but even this has its advantages (c.f. "meaningful" above).

And it isn't a gradual realization. It comes to you rather suddenly. AND THEN you have kids and it accelerates even faster.

When I'm hanging out with my father-in-law, who is in his mid-60s, often reflects on how his fast life flew. Seemed like he "was only 40 a couple years ago".

Mortality is sobering, ain't it?
