self-hypnotization-autosuggestion - chanting

I am looking for a solution for my complete lack of control - tried many things (doing lot of meditation doing 1 minute meditation - no formal meditation - but i never manage to keep it more than a few days usually 1-2 days even with only 1 minute meditation a day) what im trying to do now is to avoid doing bad stuff in hopes to do good stuff but i have no self control and always fail in it thought about a way to change that using some self-hypnosis - auto suggestion something i asked about here : https://buddhism.stackexchange.com/questions/14330/should-i-use-autosuggestion-to-make-myself-meditate now im thinking of doing chanting of sabba papassa akranam (As to the focus of avoiding doing bad i will do good) maybe during the day maybe just repeat it 108 times one time a day ? Do you think this will have a benefit ? can this "work" and cause a big change ? any tips advice on how to this ?
