I agree, in term of trading we always encounter to lose our money it is impossible that we always get profit but the most important is we got experience and we learned about that experience.
And experience will teach us real lessons in life which we can keep and use throughout our trading life. Trading without losses is like counting stars, both are far way impossible yet it can give us a brighter way in every step. So instead of thinking how you can manage trading without losses why don't you embrace it but don't let it ruin your strategy.
