The Universe is your teacher. Every time you see a cloud that makes you smile, it has taught you. Every stone that makes you look twice is a lesson. Every brick or building or face that makes you think has given you a lesson. Your life is a classroom of a higher order.
All you have to do is open the door and learn. Be accepting of the lessons that are out there. Breathe in the information, the lessons, the experiences that are all there for your growth.
