Trying to improve my self esteem

So, I am getting so tired of being harsh on myself. I keep saying I am not as good of a person as I should be which granted, I think everyone feels like that to some extent but I need to improve my confidence and convince myself that I am a better person than I think I am because I am a better person than I think. So starting today, I'm not saying mean things to myself and think of positive things of myself. I think it will really help me in the end.
