Stay out of office/work-place politics.
Be very careful what you do or say. It can either come back to bite you on the butt or kiss you on the cheek (what goes around, comes around)
Sock away $20 EVERY paycheque into a savings account and DON"T TOUCH IT. Whenever you get a raise, consider increasing the amount you sock away by the same percentage. Everytime you are tempted to use it, think about what financial emergency could crop up tomorrow and what would happen if you don't have that money on which to fall back. This is something you will never look back upon and regret.
