John Scalzi wrote an “excellent essay today on the impermanence of art”:http://whatever.scalzi.com/2012/01/30/a-small-meditation-on-art-commerce-and-impermanence — none of us know the top 10 books of 100 years ago, or even the authors of the books.
I’m betting the same dynamic holds true in popular music, or in almost every other area of human endeavor. Certainly holds true in software, with obviously even faster aging out.
Enjoy what you are doing today, work with people you like today, help make people’s lives better today, because in the long run, our efforts are largely immaterial.
You could view this as depressing but I view it as wonderfully freeing — don’t worry about making mistakes or heading down the wrong path or looking the fool, in the long run it really doesn’t matter, so take some chances today and try to make a difference now in someone’s life.
