How did the character succeed over his challenges? what did he learn from the experience?

The character succeeded by working hard, and using the skills he had learned over time. Prior experience plays a part in whether or not you are successful in meeting a challenge, but diligence plays just as important a role. If you have the will to succeed in a challenge you are given, then you can overcome almost any obstacle that gets in your way. This is the lesson the character learned from his experience. Keep at it until you are successful.
