True story: happened 10 minutes ago. Location: joint bathroom I share with my suite mate.
Not really philosophical, but contains an epiphany, so I think it qualifies.

(08:00:00am) Roommate: Hey! What time did you go to bed this morning?
(08:00:04am) Me: Morninggg, um...4?
(08:00:05am) Roommate: Omg! You have to start getting more sleep!
(08:00:10am) Me: Yeah, and two mornings ago I went to bed at 5 and got up at 10...well, at least I got over 3.5 last night...
(08:00:20am) Roommate: Why so little sleep?
(08:00:28am) Me: I have a meeting with my (PhD) advisor this morning and I'm working on a proposal, but it's my fault for staying up so late. I took a couple hours off from working yesterday...
(08:00:45am) Roommate: Gosh! With all this work you're doing, you should have just gone for your MD...
..................
(08:01:15am) Me: F***.

I walk away wondering if it's too late to matriculate for med school Spring classes...
