I remember when I was a teenager and wondering what life would be like at 50. Now I know.

You feel exactly the same, only with less time left. You're still you. You still feel the same. You still want to experience all the same things and achieve. But now with less time, you have to start triaging some goals and face reality.

I remember thinking I have all the time in the world. Now I don't. So I guess that's the main difference.

Also, I used to hold the illusion that I'd always have my family and parents to talk to. But that's not true either.
