I believe on this rules as i always remind myself copy what successful peoples did and share to us so the ending will be the success also .but i do believe it depends on the people on how he will applied it .So many people applied and the question is : why they're not become successful in life . I have only one answer in my own opinion . how they commit on it or they just applied without commiting 100% to it.
I have an advice ,if you follow this rules of success you must commit doing it ,do with your heart and repeat .that's what i learned from success seminars.
