The fastest way for a beginner to get settled is a demo account. Even there, the trader starts to develop some habits and new qualities. If they are good and have a positive effect on both trading and the person - then they should be developed further. If they aren't, then they must be immediately changed or even eliminated. The trading journal also helps to follow yourself and your habits. Using it, you'll be able to analyze the problems and find your weak points. So, I recommend keep trading journal to all beginners!
