I have for many years had the habit of waking up very early in the morning for some quiet time alone. This involves journaling, reading and time for reflection. I feel like this time in the morning sets the stage for the whole day. It is a quiet digging down.
We discovered Julia Cameron's Artist's Way series books a number of years ago and put morning pages and artist dates into practise. Morning pages involves writing three pages in a cheap spiral bound notebook every day, first thing in the morning just what ever comes out. It is like running the hose awhile in summer before you take a drink so you don't end up drinking the crummy hose tasting water. The artist date is a once a week excursion out for a few hours just by your self to do what ever gives you some creative pleasure. It could be a walk in the woods, a favorite coffee shop hangout, or a visit to a museum. The important thing is that you go alone.
Doing morning pages and artist dates along with regularly getting up early in the morning to have some time alone are ways I have found to take care of my self. I have had plenty of crash and burn artist friends and I am doing what I can to live to a ripe old age.
