If you want to see a change first you must make one. One of the biggest mistakes that people make is expecting others to change without looking inside themselves and changing as well. In order to get changes you need to make changes, and if this is not done then you may spend your life wondering why others will not change for the better while conveniently forgetting that you did not make the same effort. You can not and do not control what other people think, say, or do, but you can control yourself. Making positive changes will bring about other positive changes, and before you know it every aspect of your life will be different and more positive on a daily basis.
No one is perfect, and we all need to make some changes which will help us become better people. Expecting others to change is a futile exercise because you can not control someone else. Making a change yourself is the only possibility, and when this happens you may be surprised at the results. Think about one thing you could change about yourself or in your life and then work on this goal. Once you have managed this then you can move on to another change, slowly encouraging personal growth and making you a more positive person over time. This will attract others who are also positive, and the changes you make to yourself will be reflected in others. Don't expect to see a change unless you make one.
