We should all feel confident in our intelligence. By the way, intelligence to me isn't just being book-smart or having a college degree; it's trusting your gut instincts, being intuitive, thinking outside the box, and sometimes just realizing that things need to change and being smart enough to change it.
You can't connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something - your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.
