Gain confidence in yourself and in the fact that there is nothing wrong with you, despite the claims of others. You will notice the strengths that you didn't see before and learn how to use them.
Be more aware of your lifestyle, work, and communication approach (“why I do things the way I do"). Be more likely to make good choices that won't lead to disappointment in the future.
Minimize conflicts and get rid of excessive expectations and complaints about loved ones. Better study the psychology of other types of people — their outlook on life, motives, and actions.
Understand what other types of people expect from you that didn't even occur to you. Learn what to do to get along better with people around you, and have them help you achieve your goals.
Learn to negotiate easier – you will see the strengths of other people, not their shortcomings.
