If you have negative thoughts in your head, it’s possible you have people around you who are stating the same types of negative messages about you, even close friends and family. As you’re improving your self-esteem, if it’s possible, minimize contact with people you notice are saying negative remarks to you, even if they are close to you or are at work.  Think of negative statements from others as ten-pound weights. If you put on a ten-pound weight for every negative statement, and you are surrounded by people who put you down, eventually it becomes more and more difficult to lift yourself up. Removing yourself from the burden of having to listen and relate to negative people will make you feel lighter because you do not have to bear the weight of their negative comments, their negative judgments towards you, or their unwillingness to treat you with respect. Learning how to be assertive can help increase self-esteem. Assertiveness helps encourage other people to treat you with respect, which will help encourage positive self-esteem. In short, assertiveness stops people’s other bad behaviors from having an effect on you as well as helps you have healthy communications with the people around you. You can utilize a few different techniques to practice assertiveness: ” Instead of saying “You didn’t take out the trash last night,” you can state, “I feel upset when promises are made and they aren’t carried through.” The first statement can be taken as an attack and increase the listener’s defensiveness. The second is sharing your feelings, and letting the person know what he or she did to contribute to those feelings. Consider how the person you are speaking with feels, and be willing to strike an agreement that pleases both of you. For instance, if your friend asks you to drive him to the store, you can say, “I can’t right now; I have a class. But I can drive you afterwards. Would that be okay?” You can certainly say no, and you can stand up for your rights without having to yell, and without having to give in....
