Your eyes are like cameras, constantly sending pictures to your brain. Everything you look at, everything you ever see is "_ click! _ " stored in your memory. You've got more memory than all the computers in the world combined! Just think about that for a moment.
When you have a computer, and you're surfing the internet, you don't download every single bit of information junk you come across. You just download things that are worthy of your time, things that hold some kind of usefulness or beauty or entertainment... Otherwise your computer gets cluttered up with all kinds of useless stuff.
The places your thoughts travel make you what you are, or will yet be. Watch where you go, for as a man thinketh, so will he become.
