There are so many reasons why more people don't work towards advancing in SFI - one of the biggest reasons is that they don't see the perspective. People want quick money earning. Simple, they don't realise that it takes some time for this job. They give up too soon. Some of them don't have time, but most people just are not persistent.
If you want to work towards advancing in SFI you have to commit to the job and success will come.
