Patterns comprise the high level vocabulary programmers use to talk about abstract design. If you are reusing an abstract solution, it is helpful to refer to it by name. If you invent a pattern, it is professional to do a little checking to make sure it hasn't already been given a name. If it has been named, then the description may be useful.
After you code even a tiny bit, you will notice yourself writing something similar to what you coded before. This is a pattern. Even if it is a tiny pattern, it is worth noticing. Is there a better pattern? Do you see certain tiny patterns cooperating together to solve a larger problem? Well next time, when you want to solve larger problem, the entire pattern comes into your mind as a single chunk. Fleshing out the detailed lines of code becomes mechanical.
The more you notice patterns, the easier programming becomes, and the more you will appreciate some of the biggest and best patterns worked out by other programmers.
Try mastering the MVC pattern. One way or another, variations show up all over the place, even in tiny design decisions.
