Over the years, I've been watching how people use PCs, trying to determine the difference between those who are comfortable and adept at it and those who are still a bit awkward. Although experience has a lot to do with it, attitude can be even more important.
Some people approach PCs very mechanically, issuing commands sequentially as if by rote.
Others are able to steer their PCs in the direction they want it to go, much the way a bicyclist leans into a turn or an experienced pilot glides an aircraft to a smooth landing. The mechanical approach has its place, but I find going with the flow to be most effective because it's more natural. What's more, a lot of today's programs and equipment come with little or no documentation, so you're often forced to figure things out on your own. But it also allows you to type in the actual cell numbers, which is how some people approached it. It worked, but it was error prone and tedious.
