no lah. i just like to read so buy a few books but i have no practical exp. however i have 2 FS master frens who provide the guidelines here and there but still at best i am still below a trainee.
however after i study FS, it is not as miracle as FS master try to protray. if u set a good FS settings but the ppl dun wanna change their thinking and habits, the FS settings will be negated soon to just 3% or 0%. However if the person do a proper FS settings and complete it with a positive change of habit and thinking, the changes can be up to 30%.
this 30% is not spectacular but for some ppl who is in the borderline, this extra 3-30% make be a make or break for them. for example in exam 49% is fail but if the teacher can squeeze that 0.5% mark for the students, the student will pass.
next group are those who are scoring 89 marks for exam and is just 0.5 mark away from distinction, if the teacher can squeeze the extra 0.5, it will be a distinction/A/B marks for that person.
Now in the overall picture in life, some ppl may need that 0.5 mark to get a scholarship, get into the course of their choice or even that 0.5 mark may determine if they will pass the whole course (some course, 1 subject fail = all fail, etc. Driving test)
also FS can only bring out the potential or increase the efficiency in you, not create nothing out of thin air. if you are worth $1 now, 30% = 30c. however if you are worth $10, the 30% = $3.
hence incorporating all these as factors, some ppl are able to see massive returns while some cant see much. A begger cant become a Emperor but can try to be king of beggers.
