Redundancy is a good thing but not if all your firestarting supplies are in the same place! I'd supplement your kit with redundant firestarters in other places (matches in a match safe on a key chain / carabiner, lighter in a pocket, etc.). Along with that, practice, practice, practice. I like a small cup of tea at lunch and try different methods and fuels each time (I work in the woods so it's easy for me to get in some practice time). It's especially challenging when it's raining so a thermos of hot water back at the truck comes in handy sometimes:)
