I think those six lines have the solutions to 95% of the problems a beginner might have. The other 5% would probably involve a poorly engineered or poorly executed pipe.Dry your tobacco more than you think you need to.
Pack it looser than you think you need to.
Smoke it slower than you think you need to.
Tamp it less , and more lightly, than you think you need to.
Clean your pipes after every smoke, using pipe spirits of some sort.
Don’t worry if you have a few relights.
