You can be hungry without becoming hollow.

Wanting a great deal is not the problem. The hollowing happens when the wanting eats everything else, when friendships become networking, rest becomes guilt, and there is nothing left in you that is not pointed at the goal. You can keep the hunger and keep an interior at the same time, and the people who manage it tend to last longer than those who do not.

Check whether anything in your week is still there purely because you like it. If nothing is, add one thing back, and protect it as firmly as you protect the work. The hunger will survive the interruption, and you will be better company in the meantime.
