I need to understand how to lose weight fast

Sometimes I am not sure if I do the right thing in life and that is really sad for me. I try to make good decisions but sometimes there is nothing I can do to make sure that I have done the right thing. Do you know what I mean or not? It is really driving me crazy and I want you to know about this. Maybe one day you will understand what I mean. The problem is that I try to focus and choose properly but there is no guarantee that it will pay off. Recently I have bought a lot of books and magazines that were supposed to help me and explain how to lose weight fast but I am not sure if this was the right decision. I have lost a lot of money on it and I am not even sure whether it will help me or not. I think that I will have to look for some information on this subject. I want to learn more whether it is good or not. Maybe you can recommend me the best books explaining how to lose weight fast. Thanks to this I will have no problems whatsoever with losing weight. What do you think about it? I hope that you will help me as otherwise I might never really lose weight and that would be a tragedy. I need to achieve my goal and with your help it will be easier. Thanks in advance for all your help, it means a lot to me.
