Every time you lose money in trading that loss is permanent - it disappears from you life forever. Lets say you lose 1k - you will never see that 1k ever again in your life. You may think (via cognitive dissonance) that you can always recover by making a 1k profit on the next trade but you that would be impossible.
If you really think about this the implications will shock you.
