One should never assume that it's impossible to slow down, or that by doing so, someone is going to shame you for it. Learning to stay focused isn't going to lead you to less work, but it will certainly help you to manage stress, allow you to do more, and generally provide a smoother working experience.
I'm settled into the first stability I have ever had as an adult. I have been living in the same place for the longest time since I left my childhood home. I am mostly glad I decided to live, and vastly grateful that I managed to pay into Social Security every year from the age of 15 to the age of 53. Most of all, it is good to live without hiding.
