Advising people from reading results rather than from personal experience is better to be avoided. Beginners need to balance theory with practice and the most powerful action for beginners in trading is to try on a demo account.
In this trading discussion board there is a topic created by a senior account regarding what beginners should pay attention to in trading.
Balancing is very important, experience is the key to getting better, you can't be a great trader with just theory, but experience itself without proper theory will not be good neither. You can make someone shoot a ball with their heel for ten thousand times, and they will still be worse than below average person who shoots normally on the ball, but if you show them how to shoot the ball, then they can kick it better and then do the ten thousand shots and they will be amazing at it.
This is how NBA players work out too, they hire shooting trainers and do 10 thousand shots and get better, why hire someone if you could just shoot at home gym and be better? Because you need to learn the theory AND also gain experience.
