I'm not a part of a business, but rather a graphic arts student. I currently don't need a board for work, but I do a lot of other activities to keep track of.
Before I was doing it on the Sticky notes app on Windows 10 like this
The reason I joined Skillshare was to help me improve my skills in graphic arts, and other things. I'm glad I took this class because a Trello Board will help me be more organized with my tasks.
I know it's more than five tasks, but I work on each one, one at a time, and even then only a small part of the project at a time. I do get a lot of things done usually though, so I think my workload is okay for now. As a bonus I made a board of my TV Show's schedules since I tend to get behind on them.
I find this tool very useful, thank you for sharing it!
