Find out what the NSA really wants to do.....
If you aren't angry by the time you are done, then you are truly a sheep.
Never say anything on the telephone or in any electronic communication that you don't want overheard, copied and possibly disseminated to others.
If you don't wish to be tracked: Leave your cell phone at home....Not turn it off, but leave it at home.
If you use a burn phone (I don't, not worth the trouble)), NEVER have it on at the same time as your main phone...if possible, never have them in the same area. Keep them a mile or more apart.
You can consider email, encrypted or not, to be as private as a postcard.
The only reasonably secure communications are those done face to face, far from any electronic devices. Like in the middle of a field or a cabin in the woods.
I really don't have much to hide, so I don't worry about that which I cannot control. But if you do, or if you have communications you wish to be private, then never use any electronic form of communication.
It's that simple.
