fear results mostly from a lack of preparation :) what would bruce lee say? If you know thy ennemy better than he does (mr sun) and that you know that you prepare yourself to any fight 10'000 time harder than he did, what have you to fear but to kill an innocent?
when you walk in the valley of the shadow of death... be careful to not fall on the quick bloody sands of death, unless you know how to walk over the bamboo trees :).
