I've been training MT for a while now - only a couple of times a week, but for more than two years. Yet I'm still a punching bag, whether it's while sparring, doing live rounds with pad feeders, whatever. My technique's there. I've got enough conditioning to get through. But I can't seem to take the fight to whoever's across from me. Is it possible to "learn" a killer instinct, or is it something you're born with?
