Work hard, play hard. - My dad on the college experience.
Even if you chose not to decide, you still have made a choice. - Geddy Lee (Actually, this quote might have been in the same card from my dad when I went away to college. He's an awesome dad.)
Remember who you are and what you represent or written: RWYAAWYR. - My mother when I would leave the house...and to my friends. I think she realized it was good advice early on. I don't think anyone minded the reminder either.
