What are the best ways to increase focus?

According to me, if you want to have complete focus while doing your work, you can start by meditating before you start your work and while doing that focus on your breathing. Do this for 10 min before starting any work and by doing only this exercise you will start to see changes in just a few days. This is something that worked for me, try it yourself to find how it changes your focus span.
