Potential unexpressed turns to pain.
There are no mistakes in life, only lessons. There is no such thing as a negative experience, only opportunities to grow, learn and advance along the road of self-mastery. From struggle comes strength. Even pain can be a wonderful teacher.
When you fall, feel the pain. And then stand up. You were born for victory. And failure has no place in your world.
People can be happy while they are going through great pain and adversity. There's no pleasure evident in their external lives yet they are content on the inside. And conversely, tons of people are surrounded by pleasure (fast cars, nice homes, great clothes) but there is no joy within. So choose to be happy.
