Yw: Good OPSEC is principle based. You are already ahead of the game by knowing it's super important to learn best OPSEC practices if you are going to use technology in the world we live in. 

Just remember it's all about YOUR specific threat model. There are basic practices, yes, but most people are not running from the gov (which is very hard to sustain for any extended period of time). 

Most people don't need to go full-on ghost or have a most extreme threat model. If you sacrifice too much convenience when it's not necessary, you will burn out. 

You have to take inventory and decide in what areas of your life it is more important for you to sacrifice convenience for extra privacy and security and to what degree.

Take your time. Go at it steady. You don't have to know everything to get started.
