This topic is inherently difficult because it creates division due to it's subjective nature. In other words, people like different things. While we may share similar likes and dislikes, it would be almost impossible for another person to be identical with another in this endeavor. Interestingly enough, while our interests may be as varied as mankind is, the base emotion that drives us is the same. Mozart and Picasso had vastly different pursuits but both were driven because of the feeling they achieved. The basic emotion is central to all that we as humans do and achieve. Without it, we may have become lost to the pages of history before anybody was inspired to write them. An important note is that while happiness can be derived from almost anything, finding something that repeatedly brings happiness by sheer memory is the greatest prize. So make your pursuit worth while.
