One of the important things about careers is that things change. Your vision for yourself and what you want to do has to deal with time, technology, and more – at times within a few years.
At the same time, being aware of the history of what you do with your life is critically important. Industries, jobs, personal callings, etc. do not spring fully-formed from nothing. They have histories, often long histories, and understanding these is vital to your success and happiness. You can't create a blockbuster movie without understanding the early blockbusters (Jaws, Star wars, etc.), you won't be a successful sports writer if you ignore the successes of the past.
So your challenge this week is to play the history game.
