    We've all heard about the power of our attitude, and it's our attitude that determines how much we succeed in life.

    All the things that you have been through, all the people you have met and interacted with can have an impact on your attitude. If you think that all these factors have molded you into a person with a poor attitude towards life, there is no need to worry.____

1).Identify and understand what you want to change.

    The first step towards change is clearly understanding what needs to be changed.____When it comes to changing your attitude, you need to do an honest and in-depth self-evaluation so you could point out exactly which of your traits need to be improved or totally changed.

2).____

    Find someone who has the kind of attitude that you want to have, and let his or her life give you inspiration and encouragement to move beyond your temporary failures in your journey towards becoming a better person.

3). Choose the right company.

    As they say, “Bad company corrupts good character.” You don't expect yourself to be able to change if you go on surrounding yourself with people who possess all the negative traits that you want to change.

4). Believe that you are able to change.
