Thomas Jefferson wrote, in the United States' Declaration of Independence, that
"We hold these Truths to be self-evident, that all Men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
So the pursuit of happiness is an inalienable right. Everybody is "allowed" to pursue being happy.
This is great news!
Now, which way does happiness lie?
No... really... Could someone point me in its direction?
Ummm... And... if I'm not sure where happiness lies, or what it looks like, then how do I pursue it?
