Choose the mountain you want to climb: don't pay attention to what other people say, such as "that one's more beautiful" or "this one's easier". You'll be spending lots of energy and enthusiasm to reach your objective, so you're the only one responsible and you should be sure of what you're doing.
Each human being has been granted two qualities: power and gift. Power drives man to meet his destiny, his gift obliges him to share with others that which is good in him. A man must know when to use his power, and when to use his gift.
