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.
The whole course of things goes to teach us faith. We need only obey. There is guidance for each of us, and by lowly listening we shall hear the right word. . . . Place yourself in the middle of the stream of power and wisdom which flows into you as life, place yourself in the full center of that flood, then you are without effort impelled to truth, to right, and a perfect contentment.
Keep a grateful journal. Every night, list five things that happened this day that you are grateful for. What it will begin to do is change your perspective of your day and your life. If you can learn to focus on what you have, you will always see that the universe is abundant; you will have more. If you concentrate on what you don't have, you will never have enough.
