No, no, no! You are completing tasks the productive way. You are using tools you have trained with, and you solve each problem as quickly as possible. Don't listen to the purists. The "best tools for the job" are the ones with which you are most effective. The article's description of "the way problems should be solved" is a doomed path whose end is usually quiet failure. You will be assaulted by perfectionism and inexperience, which is a deadly combination. I know this from personal experience with my own failures.

Avoid my mistakes by sticking with tools you have trained with. I'm not saying "don't learn", I'm saying learn wisely. The road to mastery is long, requiring time and dedication. If you have not mastered a tool, don't base your strategic plans around it, otherwise you will be defeated by all the details that only experience will reveal.
