First off please try to review your question prior to submission, I don't know what the word "Pleasue" is, I think you meant pleasure.
I write on hubpages, because its what its here for, to share with others my long lived life expereinces, my discoveries, my knowledge, my world views, and so many other countless reasons.
The last reason I've come here is for earning an income, because not everyone is going to be such a great success at that part. Just like in any facet of living there's going to be those who go above and beyond the call of duty. There will be those who get to be in the spot light, and receive great honors, and than there are those who just won't make the cut.
I'm truly looking to get my words heard across the world and back, and that's my truest purpose on hubpages, for I never know when the next day may be my last.
Awesome question by the way, thanks for sharing with us.
