All the reason you'll ever need
My daughter wrote me a letter last night. She was crying in her room and didn't want to tell me about what made her upset. So instead she wrote me a letter.
To paraphrase - she didn't want me to smoke any more or chew tobacco. She didn't want me to die. It makes her sad when I do it and she begged me to stop.
Is there any reason in the world greater than that? Is there anything you can say to that? No.
There's nothing to do but quit.
And that's what is happening now. Day 3.
