I have a particular fondness for tip number six:
Buy experiences, not things. Spending on experiences makes people happier than spending on things. Things get broken and go out of style. Experiences get better every time you talk about them.
And a cool thing is...even if the experience wasn't all that great, sharing its story and laughing about it makes it a good experience after all.
Truth is...I personally prefer to give (and receive) experiences as gifts, and now it's nice to have corroboration.
