Experience always starts at losing that's why it's better for me to see newbies having a tough run while they progress.
I agree with your points of view. Mistakes improve a man's knowledge and experience. It is important to learn from your mistake and if you make the same mistake simultaneously then you are not concentrating. Every time a trader makes a mistake a short note about it should be taken so that he can improve his strategy by finding out the reason behind that bad trade.
but experience could be obtained by other means like reading other experiences, its not always needed to have first hand experience to be able to contain any problems.
because after all thats gonna be expensive experience to learn and not everyone could afford that.
its also why its better if we could just learn from other mistake, to keep our capital from decreasing, and also to be able to have higher chance of proffiting.
there's reason why many veteran trader recommend to skim through some books first because its essential in increasing our experiences.
Reading books can give you knowledge but not experience. You can be motivated by reading how others enjoy swimming or driving a car but you won't get how it feels until you actually do it. Having knowledge and experience is not the same thing. An experienced person seems knowledgable but a knowledgeable person can be inexperienced. You can learn from others mistake but it won't give you the confidence to face the challenges.
