Joe Vitale, known to most for his fame in The Secret, has been around for years doing what he does best - making sense of what blocks us most.
I recently listened to Expect Miracles (not cheating, it is an audiobook). Anyway, he talked about the importance of gratitude. Frankly a lot of metaphysical gurus talk about that and just because it is a popular theme doesn't discount it's importance or relevance.
At one of his lowest points, he talked about being grateful for his pencil. With his pencil he could write his ideas and with the attached eraser, he could amend them. When he got truly intune with himself and his pencil, he realized just how much he really did have to be grateful for.
