I love listening to song mixes on youtube. (particularly Chillstep Selections) There is something beautiful about all the different songs and how they are all blended together. By being put in the 1-2 hour mix, all these songs are now apart of something larger then themselves. And the whole mix is significantly greater than the sum of their parts. This mixture effect is found in so many things.
When a company is trying to save money, they introduce a variety of different cost-saving ideas, and usually implement a mixture. Movies / books are often sold as a collection, and some of the most famous books are just a collection of short stories. It is no wonder that TV series are such big hits, as they are built from season to season, episode from episode. This gives the directors a chance to really develop the personalities / traits of the main characters. In Broadway shows, a combination of dance moves and songs makes up a routine / performance.
These are all the building blocks of life, stacked one on top of the other. A nice thing about most of these things, is that if you particularly like a certain section, a song, a chapter, an episode, you can go back and rewatch, rewind. But for life, there’s no rewind button.
