I only used front brakes, even on gravel, except for emergency braking. But that's 40 years of experience or in other words, mistakes. 6 months experience is just getting started. In addition to experience, properly functioning brakes are a must. With experience comes not over reacting when you feel that front tire slip which is where most get into trouble. In other words they panic. I'm not sure there is a way to teach this except by failures and then the rare success. But straightening the bike up is key. Dirt bike riders probably have one big step forward in the use of that front brake in relation to the rear. But I won't even bet on that but think it would be true.
