One boy and one girl, one working, the other sleeping. When we are busy, we should first confront our responsibilities and not run away from them. When one is working he is making big progress in achieving his goal. Great things are done by people who worked a lot into the night, not loosing time and sleeping.
The girl will have much more problems if she prefers to avoid conflicts and hard work, sleeping the problem away doesn't work all the time. A good way to make the best of our time is to plan our activities and respect the schedule as much as possible.
