Try to be as generous as you can be today. Your generosity can open up doors and make people remember you in an extremely favorable way, which could come in handy soon. So step up and be the first one to give someone a compliment. Loan a friend a few bucks, or offer to lend a coworker a hand on a particularity ambitious project. The more outgoing you are with your time and goodwill, the faster you'll start to get results back: in the form of very good karma.
