A caveat: if you have more than ten directs, it's okay to start with biweekly O3s. Trying to find, say, 8 hours (16 half hours for 16 directs) in your week may be a bridge too far. Spend 8 to 12 weeks allowing your schedule to absorb the 4 hours a week, and then try moving to weekly. (This habit of stressing your calendar will prepare you well for executive life, if you aspire to it.)
