Poem on how to live a life happily

Hi Lewis,

Pretty soon, I wouldn't be addressing you only because the title of this blog will soon be changed to "My Grandchildren" and you will have a competitor and I a problem. Who do I address my message to? Anyway, for the moment, you have my sole attention, and here is some advice to you from one of your aunt how to live life. Good advice. You should take it "seriously" if I were you:

---

Life is short,
live simply,
Forgive quickly,
Love truly,
Laugh yourself silly,
Be healthy,
Smile always
And be happy...

---

I will see if the author of this nice poem wants to be identified by name, and if necessary, edit this post later so if you find the poem (advice) useful, you can thank that aunt in person.
