Confusion is always the most honest response.
There is only one thing about which I am certain, and that is that there is very little about which one can be certain. It wasn't until late in life that I discovered how easy it is to say, I don't know. It is astonishing how much more anxious people are interested in lengthening life than improving it. Little minds have little worries, big minds have no time for worries. Believe that life is worth living, and your belief will help create the fact.
