1.  Be authentic.  Some people use gifts as part of doing business or politic.  But I prefer to be genuine.  If your boss or your co-worker or a recruiter has been supportive then now is a good time to say thank you. 

2. Be appropriate.  Don't give a present that looks like you expect something in return.  Under $25 is a good guideline. 

3. Be grateful.  Give gifts to people who have helped you whether they are the security guy or the CEO.  Look for ways to show you care.

4. Be unique.  Think of gifts that someone will notice.  Homemade chocolate sauce.  A book that inspired you.  A unique gadget.

5. Be creative.   If you're not working you may not be able to buy gifts even small ones but you can still say thank you with a card, an article or a single truffle in a simple package.
