Hi One of the simple ways to improve your self esteem is hypnosis. It can help you to believe in you. I used hypnosis a few times in my life for various issues I had and it seemed to work quickly. I used it about 2 weeks every day and could see some results after the first week
I tried going to hypnotherapists but they were too expensive and I started using recordings and they are great. I used these guys as they record high quality and effective recordings. sorry guys I can not insert any links at the moment so contact me for details I think it was on unknownhypnbosis website.

I hope I am not going to get banned for this link but just want to help
by the way do not overdo it.

regards
Mike
