Take a gun course, learn how to shoot and get a gun for your home. Take a concealed carry course, get the license and carry a gun with you.
Martial arts will not do much for you, even if you spend the majority of your life focus and time trying to "master" a martial art. A gun is MUCH more effective, MUCH quicker to use, with MUCH less investment. Just get some practice shooting and some situational training.
"Intelligence and intuition" is getting a gun before you need it, before you are attacked. Sorry to be so blunt but what kind of intelligence and intuition do you think you can use while you are being attacked?

Some had a gun to defend themselves, some didn't... and don't rely on the police to protect you...
