Lol,
Honest bob that is not really that sound of advice,
Saying technical analysis is silly would be the same as calling game theory silly, xing out either one completely is just screwing yourself in the long run, thinking that technical analysis is worthless will only lead to one thing, You never taking the time to learn it, Everything in trading is important and has a play on the market,
I know plenty about it (I even have the bible -- Murphy's TA of FM), and I can confidently say that technical analysis has no rational basis. It is consists mostly of "theory" based on unsubstantiated speculation (Elliott Wave Principle is a great example of this), and it is a classic demonstration of confirmation bias.
No trader can explain how or why it works with both rational explanations and empirical evidence, and that puts it into the realm of magic and superstition.
Game theory, btw, is a theory of decision making. It is similar to the method that computers use to play chess.
