If I would say there's a pattern of sabbaticals that are done right, it's a focus on mind and body, and it's resting both, and taking care of both. For sabbaticals that did not go so well, I would say, the pattern is to load it up with expectations, like 'I'm going to finish a book' or 'I'm going to read these 10 books' or 'I'm going to write a new business plan.'
