The most valuable lessons are the ones you don't want to learn because you know they will hurt. They are the result of pain. Pain comes through experience and leaves scars. 

Scars are visual and mental reminders of painful moments.

Pain hurts. Dealing with the results of pain can be challenging because it opens us up to more potential pain.

When you have experienced pain, you want to help others avoid similar pain in their life. Stopping or preventing the pain is the goal. The struggle is some lessons are best learned by experience. Even if the experience will cause them pain.

Even though pain hurts, it is a part of life. We all experience pain moments. The real test is how we learn from those moments and translate pain into positive action.
