Can't Stop the Grown-Up Train

Why is it that my friends are graduating, finding jobs, getting married, having kids...?  When did we all grow up?  Maybe it was that 10 week period in Ecuador...  I just feel like I missed something, and can't figure out how yesterday I couldn't decide what party to go to, and today I am worried about my future career.  Time really goes by so fast.  

My brother turned 20 today.  I am graduating from college in about 2.5 months.  I have more than one friend who is married or has kids.  Matt just earned his bachelor's degree.  

I don't want to go back, I want to keep moving forward.  I am just amazed at how fast the time has gone.

Sooooo, what am I doing with my life?  I really need to work on that question.
