When it comes to commitment, there are really only four types of people:
1. Cop-outs. People who have no goals and do not commit.
2. Holdouts. People who don’t know if they can reach their goals, so they’re afraid to commit.
3. Dropouts. People who start toward a goal but quit when the going gets tough.
4. All-outs. People who set goals, commit to them, and pay the price to reach them.
