On the Marriage chapter, the author speaks about the rewards of spending time with oneself and the long time benefits. It's like the saying that you have to love yourself before someone can love you, and I think that is what this whole chapter delves into. I also think that it is important not to lose oneself into a relationship and this chapter could also be interpreted as saying that.

The chapter on love is all about loving and caring for the person but also giving them personal space. It tells us that this helps relationships thrive as the people grow separately and together.
