Very true, many people have dreams and desires, but they never go beyond just saying it. But what are you going to do about it to make that dream come true? You have to set small goals, make a plan to achieve them little by little, be consistent so you can really take hold of them, and I understand that there may be many personal circumstances that can complicate that goal, but it's very important to turn what you say into real actions, if that's what you want.
These people need to realize that dreams and desires are not equal with goals and also need to learn what goals are and work towards realizing them. It's a long road, but without it, they will always be "empty talkers", wasting people's time.
