One of the saying which I know against the word winning is “Winners will not do different things; Winners will do things different”

First, with closed eyes, imagine yourself at the place and time in your life when you felt smart, good, presentable, and powerful as a person in the company of other people. Spend some time doing this.

After that you can give yourself some verbal suggestions like these:

• I am a winner.
• I attract friends.
• I am friendly.
• People are friendly to me.
• I am cheerful.
• I am enthusiastic.
• People like me.
• People respect my opinions.
• I impress people.
• I feel good with people.
• People feel good with me.
• I am popular.

All the above points should give you a self appreciation with positive attitude, if you become addict for self appreciation then its difficult for winning. So take care about the self appreciation

Mentioned point will not entirely change your personality, but it will give a small amount spark to ignite your winning personality
