Greed is a major factor that makes people to lose in trading, they're always in a haste to make profit, in the end majority of them will lose their funds. People are looking for fast ways to make money and they will think that trading is a shortcut to their aims, they will enter with confidence and without experience they will lose all their funds very fast. I thank OP for listing out his strategic plans to reduce trading loses and I agree with his points, it shows his level of experience. To summarize his strategies I'd say that every trader needs to remove the mentality of get rich quick in trading, better to trade with small amounts to minimize big loses.
That is a problem that is difficult for a trader to overcome and maybe what distinguishes experienced or professional traders from novice traders in terms of controlling themselves so as not to be so greedy in trading.
The motivation to gain wealth in trading is not a problem as long as they are able to control themselves and not get involved in trading in a much more greedy way.
Slowly people can improve their trading skills to be better and that needs to be done by training mental readiness in combining existing knowledge.
Without having that, it is difficult for beginner traders to gain experience in trading because if they continue to force it and they experience losses, it will make them increasingly fail to achieve good skills.
