Stress is a part of any job. It is a perspective that is compounded by your economics, your responsibilities, making your way through the times and common experiences, and then you get your day. Each one of those components has an interesting dynamic and interplay with each. Staying present is the key, focusing on the good portion of your responsibilities (where possible), loving the time you get on your own.
I know this. I have thought this many times. And I continually have to check myself. Find your ritual, find your cues, find the things that bring you presence. You deserve to be the whole you in this experience. I wish you all nothing but peace.
