"Take it to the limit" and "Be all you can be" and "Just do it" - unless you are gay, transgendered, female, mexican, poor, or just want to do something that will make somebody uncomfortable.
"Live life on your own terms." - but don't disagree with corporate culture, religion, your party leader, the two major parties, company policies, big oil, etc... or when you will make somebody really uncomfortable
"Be true to yourself" - except when it makes others feel really really uncomfortable and might inspire a harassment suit.
"Live and let live" - except when there is money to made suing people or when somebody makes you really really really uncomfortable (see also be true to yourself)
"Be happy with what you have" - but look as good as the models in the fashion magazines and have all the gadgets that in the tech magazines (or else you might not feel comfortable marching to your own tune!)
