You can decide to spend 30mins or 12hrs, what you should forget is, it’s your own business. The more time you spend enlightens more about SFI. I will advise that you should spend between 4 to 5 hours in the beginning days at SFI (1 Month). But later when you are really sure about what SFI entails then you spend less time to do your daily task.
