I understand that multitasking would help you save time and manage your business hours effectively however i have to say that i disagree. If you’re multitasking, there are cases wherein you won’t be able to focus on both tasks. This would sometimes lead to mistakes and errors which will then cause you to correct your mistakes which clearly means that you’re wasting some of your time. However for the rest of your points, i totally agree with you especially breaks. This is the time wherein you can relax your mind and come up with great ideas with regard to your business.
