Click

Malcolm Gladwell recently extolled the power of thinking without thinking in his book blink. I think his next book should be called click, the power of running a computer without knowing what you are doing.
Conventional wisdom would suggest that you know how to perform an operation before you attempt it. Otherwise something will blow up. This fear of experimenting is the main reason why folks can't get things to work on their computers. But as far as I can tell, the modern computer and the software that runs on it is designed with a new idea in mind. When in doubt, just click. It doesn't matter that you do not know how to achieve a desired result. Just click until you get the machine to do what you want.
If you are in doubt about running a computer this way, watch any sixteen-year-old operating a program or fixing a computer. She clicks. Before you know it the computer is singing.
So what do you click to get things to work? Normally you click anything that might take you to a desired result. The menu bar is a great place to start clicking. Look at the menu to see what options the program can offer. Click and see what happens. Go to the control panel and click. See what things you can control on your machine.
Most changes can easily be reversed if you don't like the outcome. If you are unsure click cancel. Try to remember where you made the change. After a while you will get good at clicking in the right places. But you won't learn unless you first click.
