When I was 40, I wrote my first book, The Pilgrimage, and I said to myself, "why did it take so long for me to write this book?" Because my dream, since I was 10 years old, was to be a writer. I said, I have to revisit my life using a metaphor, and the metaphor was basically this boy that has a dream and has to go far away to realize that his dream is close to him.
Paulo CoelhoChoose 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.
