Here is some other good advice:
Pack less tobacco in your pipe. You don't need to stuff it full. You should experience a little resistance as you draw, but it shouldn't feel like a thick homemade milkshake.
Puff slowly and take time between puffs.
Don't fear relights. You don't need to worry about the pipe going out.
Tamp lightly. Sometimes a light tamp and steady puff will forestall a relight.

Enjoy the learning curve and ritual!

More great advice.
