You answered your own question, when you said, "I'm tilting..."

Being a long-term winner in this game is NOT about how you play (X) cards... it's about how you react to what happens before, during, and after you play (X) cards. Obviously, understanding basic strategic principles are mandatory, but right now, you should be focusing on your mental and emotional control during these losing days.

LESS TILTING should be your primary focus, no matter what your stats say.
