Even if you don't have ADHD (like I do), learning how to keep yourself focused at your desk — at work or at home — can be a frustrating process, full of trial and error. What can be especially frustrating is that there's no one-size-fits-all solution for when you find it hard to keep your mind on your task, so whatever method or product your BFF swears by might be a terrible fit for you. There is, however, a wide range of methods and products that are useful for staying focused, and plenty of those products that can help you focus are also perfect desktop tchotchkes, so you can stay on task as much as possible.
Because no single solution or type of solution will work for everyone, it's worth trying different methods for staying focused, including software-based ones like apps made specifically for focusing, and physical products like chairs and fidget toys. Like I said, it's going to take some trial and error to figure out exactly what works for you, but if you're patient and give yourself the time you need to figure out what's right, you could end up with multiple seriously effective solutions for your focusing struggles.
Whether your particular trouble is getting distracted, not paying attention to the time, or just not being comfortable enough in your workspace to concentrate, these focus products are definitely worth a shot.
