If anybody tells you there's only one way to trade, don't believe him.
There's only one way to fail though, that is to fall prey to crowd psychology and deviate from your trading plan. All failure stem from either not having a proper plan or deviating from said plan.
If you are failing, and you have a plan and you are sticking to it, that means you need a proper plan.
If you have don't have a plan, get one.
If you have a plan, but are not sticking to it, it's called shooting yourself in your own foot. Someone once said, 'As long as we stopped shooting ourselves in our own foot, we will start looking like geniuses to others.'
