Smile, and the World will smile back at you;
Aim with a grin and you cannot miss;
Laugh off your woes, and you won't feel blue.
(Poetry pays when it's done like this.)
Reading Not Much Fun - The lost poems of Dorothy Parker, which after a quick thumbing seems more interesting for its abbreviated biography than Parker's poems. But she had a great gift for pun, which (for me) is always worth a closer look.
Great dialog about "giving up writing" over at first draft. I'm not really enough of a writer to be taken seriously when I propose to give it up, but the writers engaged in discussion in that corner of the world have some insights you might be interested in.
