Just Don't!

don’t talk unless you can improve the silence 
don’t talk when you can't be heard
don’t sing if the song is out of tune
don’t sing unless you can improve the song
don’t write if the pencil has not been sharpened
don’t write unless you can sharpen minds
don’t dance to the tune of indifference
don’t dance unless you can control the tune
don’t run too close to danger
don’t run unless you can go on empty
don’t think if you are still in public
don’t think unless you can make it known
don’t look like you know nothing
don’t look unless you can possess it
don’t laugh your jokes are not funny
don’t laugh unless you can make us happy
don’t drive unless everyone else is a loon
don’t drive me up the moon
don’t paint if you can see indifference
don’t paint unless you see in colour
don’t dance to the tune of indifference
don’t dance unless you can move feet
don’t do unless you can undo it
don’t do it like this again
