Yeah, in some ways martial arts is like sex- entusiasm can go a long way

Willingness to take the risk, and practice to make/ have a technique when facing the "Tasmanian Windmill".
I see some people making comments in relation to shooting "the trigger pull is funny", but if you are really proficient trigger pull doesn't matter. The BANG is supposed to be a surprise right? heavy or light trigger pull doesn't matter all that much-it is the squeeezzzee that counts Bam! suprised?- bet you hit the target if you kept your sight picture........
The sight picture in martial arts is keeping the chaos from jamming your awareness and being practiced enough to act to end the fight while staying alive. A lot of this is being able to act faster than your opponent- hence the enthusiasm/ willingness to mix it up.
Make sense to you? Works for me.
