Does Being Happy Make You Smarter?

I read today that "for years, cognitive psychologies have known that being happy actually makes you smarter."

If this is true, then it goes to follow that finding at career and job in which we are happy maximizes the likelihood of our being "smart in our work."

I also read what seems to me to be some very good advice from the 10th Century Kashmiri philosopher Tilopa:

* Let go of what has passed
* Let go of what may come
* Let go of what is happening now
* Don't try and figure anything out
* Don't try to make anything happen
* Relax, right now, and rest

Seems like good advice for calming the mind so that new ideas and stories can manifest. I'm definitely going to give it a try in the week to come!
