The law of motivation tells us that the participant must have the desire to learn, he must be prepared to learn, and must have reason to learn. The trainer finds that if the participant has a strong motivation to learn or the desire to succeed, he will be better than the others in learning. First of all because motivation can create a learning atmosphere to be fun. If we fail to apply the law of appropriateness and neglect to make material relevant, we will definitely lose the motivation of the participants.
