Be frank, if you can't find out the reasons by yourself, I think you are type of person that is not for ebiz, but for other type of jobs, maybe teachers, professionals, accountant, CPA, engineers… Your question is not a question for those who successful run an ebiz, and this difference makes you behind others right at the beginning. So doing things that fit you and you can benefit most.
