I remember the cartoon character Bugs Bunny used to say, "Life is dull as mud and not so much as a carrot to cheer me up."
Yes, there is a lot of repetitiveness to life--go to bed, eat, wash, groom, go to work, etc. Yet, during any free time we have we can choose many activities to make life less mundane. For example, I enjoy reading, going out with friends, watching TV, spending time with my family, helping others, etc. To some extent, life is what we make it.
