I know I have already been happy.  So can I say that anything I have not yet experienced is not really necessary in order for me to be happy?  Where do I draw the line.  I presume the best thing is not to abstain from all pleasant experiences that I have not tried.

But there are some which I have abstained from for better or worse.  And in having never had them, I do not miss them.  Perhaps the notion that I don't need them to be happy is all in my head, and really, since I even know that they exist, I should not be happy without experiencing them.  But those which I have never even been aware of, ah, those I clearly do not need.

I suppose we won't really know, and it is up to us which things are worth experiencing and which are not.  And that shapes our life.
