Billy - I am so thrilled for you. The degree. The job. The hickeys right before graduation. (BTW, did the concealer work? Tell us the story!)
Anyway...You did it. I can't believe how time flies. Another reason why anyone who thinks they might want to pursue their education should explore that possibility very, very seriously.
However old you are, you could wind up four years older with or without that degree you have always wanted. Its never too late. There's no such thing as too old.
The only other thing I would suggest to whomever is thinking about further or higher education is this: Go to the very best college/university you possibly can given your own personal situation. Stay away from for-profit institutions. Go for the real deal.
And as for you, Billy -- I know you went to a great school. Well done, you!!!!
