You're wrong in not using it, that was your advantage, you can never appreciate TA's if you don't bother to apply what you have learned.
Perhaps, you don't wonder why you often lose as simple buying and selling without market analysis is pretty hard to catch a better price. I'd try that before but it never works, we are just lucky if we can make a profit as mostly it ends badly. I would say that to use it, then you can see a big difference results of your trades.
