The Daily Mail reports that having your friends divorcing encourages you to do the same.
There is a theory that you become like the 5 people you spend the most time with! I have found this to be true in my own life and only after you have got rid of negative influences such as gossips and heavy drinkers do you realise how much they influenced your own behaviour.
Behaviour is a habit. Eating, thinking, exercising, all can be changed dramatically after three weeks of making yourself act differently, suddenly it will require no effort whatsoever.
Want to change something? The hardest thing is the first small step - after that it is easy. The next time someone wants to talk negatively about someone else - change the subject. Do you really want to spend any of your time on this planet discussing other people? It's boring and will drag you down. Focus instead on people you admire. List five. Can't think of five? Time to change your friends!!!
