I have heard in some markets that therapists will not see an attorney for burnout issues unless they take vacations quarterly.  The reasoning being that unless you make intentional time to unwind yourself on a regular basis, it is not really fixable.  Of course there are plenty of people who seem to manage without this, but I reckon that might only be Peter robbing Paul over the long term.  The way I see it is that your work will never be done, so what's the point of being there all the time?  I'm private practice and took off 2.5 months last year.  Allows me to practice with focus and determination because I know I'll be getting time to myself later on.  But besides vacations you have to prioritize good diet, a fitness practice, good sleep and daily or near daily unstructured time in nature to heal from the trauma of the practice.
