you have been using patterns for a while

Take this one for instance, the Composed method:

Divide your program into methods that perform one identifiable task. Keep all of the operations in a method at the same level of abstraction. This will naturally result in programs with many small methods, each a few lines long.

That's as simple as breaking a method into smaller methods, something you do in every day programming, there are many simple patterns like this one, all they do is describe the tasks you do on a daily basis.

The whole point is that by knowing the names of the patterns, you can communicate much faster, easier, better and by using them you will be a more educated programmer, a better developer; remember that a great developer is not only the one who can write amazing code, but who can communicate ideas and is able to work on a team

"the best code in the world is meaningless if nobody knows about your product."

You are already using patterns, learn their names, learn more patterns, use them and pass them on to your team, you will learn even more, by teaching others.
