I have to admit - as a Christian kid growing up in the 80s I was a big Petra fan. The other day, the song "Computer Brains" from Petra's "Beat The System" album came on my iPod. I started thinking about the truth of that song. It was powerful.
Here's the truth: our minds are like a computer. Remember the old computer acronym, "GIGO" (Garbage In, Garbage Out)? You have to be very careful when you program a computer. Even the smallest error will produce flawed results. In other words, the results produced by the computer will be no better than the quality of the programming.
People are the same way. What goes in is what comes out. Psychologists say that we tend to become what we think about most. Proverbs 23:7 says it this way, "As a man thinketh in his heart, so is he."
My question for you is: What kind of input are you receiving? The quality of your input determines the quality of your output.
If you want a positive attitude to come out, put positive information in. Hang around positive people, not complainers. If you want thoughtful, courteous, helpful words to come out, you better make sure the input you are receiving matches that desired output.
What kind of books/blogs do you read? What kind of music do you listen to? What kind of people do you go to lunch with? What kind of conversations do you have on break? Do all of these INPUTS help you grow and become a better person/leader? If not, it's time for a change!
Remember, your brain is like a computer - only much more complex. Control your input, and your output will take care of itself.
