When you start your day slowly and keep doing things at a slow pace then it becomes easier to keep the stress away. It becomes easier to focus on what you are doing and keep your priorities in mind.
When you go slow you stay in the present moment more of the time and so less negative feelings come your way and you appreciate the everyday things in life more because your attention is focused outward and not aimlessly inward towards what happened in the past or may happen in the future.
When you start your day slowly you sometimes get worried that this slow pace will mean that you get less done during your day.
But at the end of the day you most often discover that you got more done.
Because you did things well the first time and because when you go slow you tend to spend less energy on draining feelings and on having your attention bouncing around between many things.
And so you have more energy during the last few hours of your workday to spend on things that matter to you.
