We are living in the golden age of television. The past several years have seen an explosion of quality television, with more money spent per episode than any other, and more risks being taken on concepts than ever before. The golden age is dying at the hands of the so-called "Reality TV", but there are still plenty of good programs on TV. So, to begin with, I would like to say that I am not a person who hates television.
The TV is one of the key culprits in "things that will keep you from making your own thing." It is a master at pulling attention, because attention to the TV is what causes it to make money. You are keen to watch a show, which in many cases makes you keen to stick around while commercials are on. Even if it's not commercial supported, or if you can somehow bypass the commercials, the programming is still finely crafted to keep your attention.
Resist this allure. Yes, watch the programs you love. Yes, take some time out every now and then to do something relaxing or enjoyable like watching some quality serial entertainment piped into your home and warming you with its warming glow. However, if you spend 3 hours a day watching television, that's 3 hours a day you're not working on your thing. Over a week, that's a part-time job's worth of hours that you could be spending making something awesome.
So, if you watch TV, watch it with a mind to see the things that you really, truly enjoy the most, and not just as a way of taking up your time. The time is yours, not the television's, to control. Control it.
