First you're an infant, and that's a big emotional crisis.
Then you're in the terrible two's, except they last until about 5.
Ahh, childhood, you're pretty good until about 11.
Then you're dealing with awkward pre-teen crap.
It's your teens, everyone talks about what a hormonal drama that is.
Now you're in your early 20's, that's fun for a bit.
I'm 25 already!? oh my god, I'm getting old, where am I, what am I doing...
..........and so on!
I'm pretty sure it never gets better, it's all about seizing the little moments that make it all worthwhile =).
