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 moment you venture out, something takes place in you and about you. Life comes to your aid in various ways. You may not like the form in which it comes to you - it may be misery, struggle, starvation - but when you invite life, things begin to happen.
Think'st thou I'd make a life of jealousy, To follow still the changes of the moon With fresh suspicions? No; to be once in doubt Is once to be resolved.
The chief thing is to love others like yourself, that's the chief thing, and that's everything; nothing else is wanted - you will find out at once how to arrange it all.
