Dont lose intentionally. You cant make yourself a good trader by losing intentionally and then thinking what are the measures to be taken. Be realistic and put every possible effort to make thing successful. When you lose in this way, you would get to know the potential of your work and how can you tackle these problems next time.
Normally, there is no one on earth that will want to be deliberately losing as that would be uncalled for actually. The reason a lot of people tend to lose most of the time is because they are doing things they are not supposed to be doing in the first place and the most of it is not to ever trade without the knowledge and skill of how to trade.
It is pretty amazing the way people approach trading in a way like they can just blend in, learn from their mistakes and get better. Mistakes will happen even after learning, but without knowing the basics, building a strategy with those basics, and then keep learning as much as you can, you won't be learning from your mistakes, you will be failing woefully over and over again with your mistakes until you get frustrated.
