tell them that SFI is like planting a mango tree. you have to be patient. nurture it and care for it until i grows to its fullest for you to enjoy its fruits. one can not expect a fruit-bearing tree to deliver the fruit the next day or a week after it has been planted. tell them to at least spend six months or more doing all the things that has to be done in their own free time. no pressure on their part. because it is always nice to do things when one is happy and free.
