There is no wrong or right way of naming the folders on your computer. It is really just a matter of preference and what works best in your workflow. Having been doing this for a number of years though I have experimented with quite a few different ways and this is by far the one I like best. Here's a quick video, less than 2 minutes long, that shares with you how I name my folders and why I chose to do it that way.
In short, I like to keep things in chronological order by date (YYYY-MM-DD), then category, then name of the clients. By doing it this way I am able to not only keep my files organized on my computer but it also makes a work queue for me in Lightroom so I know what job is up next to edit. Once I have finished with the job, I remove it from Lightroom and go right into the next job. As I said in the title, it's a simple tip, but definitely one that helps keep things organized and helps me stay on top of my editing workflow.
