Here are 5 bullet points that summarize the video "The #1 Reason Some Men Can't Commit":
1. Happiness comes from meaning and not just pleasure. Some men who believe that pleasure is the key to happiness may be afraid of commitment, as commitment requires sacrifice, compromise, and delayed gratification.
2. Men who operate from this unconscious belief are not great candidates for commitment and won't have enough practice in the quintessential habit called "delayed gratification."
3. Meaning is created by responsibility, contribution, and evolution. When a man is committed to a woman, the commitment is not just to that woman, but to a set of principles.
4. To know if a man can commit, observe how much discipline he has in his life, how much he contributes, and how he acts in ways that are good for others.
5. Men who understand the importance of meaning over pleasure are more likely to be able to commit to a woman, as they are not self-centered and will want to contribute to others' lives.
