Glass makes a good observation here:<p><i>Since I was your age, for example, people have been working with machines. It’s not a new idea, but it’s always going to be the same problem. It’s important for you to understand the problem right now because you won’t waste time on things. How do you get to a better place?</i><p>How many times have I charged ahead thinking I was one of the first to address some particular problem? Well, a lot. It is good to step back and take a look at the problem and the previous attempts made to solve it.
