Your Shotokan Karate can be plenty dangerous enough to win you most fights. Just stick with it. Practice a little more often, Focus really hard at the dojo during your training. Go a little harder and faster and pretty soon your doubt will go away. Talk to some of the more advanced guys at your dojo. They're probably pretty confident about how they would do in a fight. They will probably give you some tips to help you win.
