The most difficult part of building a fire is getting the first spark to catch. The next hardest part is nurturing the embers and feeding them until a flame can take hold. And then, so long as you have ample tinder, and larger more dense sources fuel, stoking the flame becomes progressively easier. As it grows it begins to take on a life of its own, consuming with an indefatigable voraciousness everything in its wake. Then its only a matter of containing it, directing it, and capitalizing on the HEAT.
