I was just trying to think positive "maybe I can learn something from sparring with people". Not sure if it's the right mindset anymore. Recently I've only been frustrated.
sounded like you have all the symptom of AWS (aikido withdrawn syndrome). the treatment for that is to not think, talk, and discuss about aikido and jump wholeheartedly into tang soo do. if you still have issue, then have your friends beating you with a very big and ugly stick every time you talk or think or do aikido. it will hurt you very much but your friends will enjoy it.
just learn tang soo do for awhile. you might learn some interesting stuffs. know the word "shoshin"? you are not in a hurry do you?
