In a perfect world dividing every task up 50/50 is ideal, however, that “solution†doesn’t always work and negates specialization–completing tasks you do best in relation to other tasks. If you’re good at getting the kids up in the morning, then you should do that each morning versus switching with your partner every other day. You’re utilizing one’s talents in the best possible way and maximizing everyone’s time. Hence, the time saved can be used to complete other pending tasks or more leisure time.
