Plan your work and work your plan is something I've always been taught. Having a routine can definitely make your day productive.
Every day I start my morning with gratitude and a sip of herbal tea. My go to tea in the summer is Cool Mint. I have found my self putting a table spoon of tea in my tea bag(ball or steeper) for 2- 3 minutes and steeping that very same bag throughout the day. The first sip gets my day going in the right direction. Next, I get my body in motion with yoga. From there I start knocking out each task one by one, which helps me stay focus.
Always write down what you're going to do. This helps eliminate idle time, and improves your memory.
As you know life is full of surprises, that is why it is necessary to have a plan. So when someone throws a monkey wrench in your stride you know how to get back on track. Sip and relax and enjoy the rest of the day.
