Concentrate more, be less interrupted... and get things done.
Your cognitive load can be burdensome when you own or run a business.
Not only do you have your own work to consider, but you also have to divide your attention between that and what your people require of you.
That can mean constant interruptions, a growing to-do list, and never quite reaching the work/life balance you desire. Which was most likely one of your key objectives when you first established your company.
