Hi, I have been using the subliminal affirmations on youtube, for about a month now for self esteem I have to say that along with my 10 minute meditation I find it a very powerful tool. I was extremely skeptical at first but the change in my confidence and lust for life has been something I have not experienced since I was a young man. You do need to believe, it is not just a placebo effect as some scientist try to discredit it . You also have to do it everyday I choose to do this at night when going to sleep, give it time, patience and perseverance and trust in yourself and it will come. Thanks
