Look at this as a gift, not as a blow to who you are, or what you do...it really has nothing to do with eaither. Empty your cup, stay open to experiences like these, they really are the ones that matter the most. This will help you not to become stagnant in your developement...if you never got tapped, choked out etc you would never learn anything of value.
I cannot tell you how many times i have seen someone who is inexperienced do well against a more experienced martial artist...that includes guys off the street that virtually know nothing. Theoretically yes, a more experienced person should be able to do well against someone not as seasoned, but sparring, fighting, combat etc are so alive, there are really never any guarantee's.
Let go of all those pre concieved notions, then you will actually be free to enjoy the journey.
