Be wary of extravagant gifts from co-workers or casual acquaintances. They could be giving you something with the expectation that they’ll be getting something in return. Even if they claim there are no strings attached to this present, you know that this kind of generosity has to be acknowledged and returned in kind. You can’t afford to be obliged to anyone at this point. You should only be acting on your behalf, not to help others get ahead. Selfishness isn’t always bad.
