Exemption from compulsion. Nobody is supposed to force you to do anything or to force you to stay within certain boundaries. Essentially you are free to move or live as you please, as long as you aren't violating the rights of others to do the same. Anybody should have that right. If they choose to engage in an agreement to limit their freedom, it should be voluntary and it should only apply until such time when the agreement is canceled.
Nobody can permanently give away their liberty, it is an inalienable right.
The pursuit of happiness basically means that you can choose whatever you want to be interested in or whatever activity you find enjoyment in engaging in. You can play any game you want. Nobody can decree which ways of living are acceptable. Again, as long as you don't harm anybody else, you choose what is right for you. These are the best of principles, on many counts.
