You can spend time for learning but it's not enough, even it is good. Because you need to have practice too as practice makes perfect and practice helps you to filter many strategies from your learning, to choose a strategy that fit you most individually.

When you already learned about strategies, practiced with them enough, you will have more ability to choose good strategy, maybe only one strategy and stick with it for your investment or trading. This takes time to come to this very ending step and you can not get it at beginning. I believe none investors or traders can know and choose what is best when they are newbies in this market.
