Take a note!

Taking a note is very important when you are working. If you don't do that, you have to ask the same questions of your coworkers over and over. And you ought to write it down in a notebook rather than scratch paper. If you try to do this easy thing at your workplace, you may be much more productive than you are now.

Why am I writing a thing like this? An old guy sitting in front of me doesn't understand this. And he seems to have difficulty doing some works properly. His boss asked him to take a note, but he doesn't. I often sigh.
