A good tagline

I have just finished working on some logos which required a tagline, a one-line slogan, something brief but memorable. They made me wonder, what if I had a personal tagline to motivate me to work on a project? Something like Nike's, "Just do it" or Apple Computer's "Think different"(which has always irked me because I always thought adverbs should end in 'ly' and so it should read, "Think different-ly," but whatever).

I have a friend who used to write inspirational quotes on stickies and post them around her house to help put her in the right frame of mind each morning. (I tried that once but they fell off the painted walls and my dog attempted to eat them.) Are there any educators out there?...perhaps you've done something similar with your learners. After all, a good slogan or tagline can really inspire a person. What words work for you? Something that suggests action or a sentence to focus your creative energy? If you were to visually represent these words, what would it look like? Would you use text or images? Would it be banner size, big enough to hang in a door frame or something much smaller that could be carried around in your pocket? Would it feature bright and bold colors or a clean and crisp design? What do you tell yourself when you want to get a job done?
