On fear:

Do not be afraid of fear. Ready for a twist? Fear and excitement are one and the same. You feel most alive when you are closest to death. The fear-excitement spectrum varies according to the sense of control over the situation felt by the individual, which comes from certainty, which comes from experience. More perceived control, and excitement results. Less, and it begins to slip into terror. But the two are one and the same. Have fun out there.
