Say what would happen if these people changed their way of living

This girl never eats as much as she would like to, but she doesn't mind it, because she wants to be in good shape. She spends more than an hour a day doing aerobic exercises. In addition she takes long walks and never goes to bed later than twelve o'clock. She doesn't smoke. She must keep in shape because of her job. She is a successful fashion model. Her job is both interesting and well paid, and she doesn't want to lose it. There's another reason, too. She's going to try her luck in an international beauty contest. So she's learning to speak English and play the piano.

This man has got a family and a job, but he may lose both in the near future. The thing is he doesn't know how to plan his daily routine, so he never has enough time to do his work well. He always puts things off for another time. That's the reason he hardly ever keeps appointments and is often late to work. So it's perfectly natural that his colleagues don't find him reliable and prefer to deal with somebody else, not him. His wife and he often quarrel. Nobody's pleased with him, and he isn't pleased with himself either, but he can't do anything about it. That's the whole trouble.

What would happen if he began to plan his daily routine?

Would it be easier for him to keep appointments and do things in time?

Would other people be more pleased with him?

Would he be more pleased with himself?
