for example some people can be music masters within a year.. where others will take 20 years of practice ot acheive the same standard putting in the same relative time of practice..

Generally speaking though, if its something you are learning new, and you have average starting ability .. then you can expect to be a master in no less than 15 years really. it takes THAT long including study time of around 7 years and 8 years of semi study and hardcore experience.

you can be very very good at something after only 5 years.. but you cannot possibly be a masterwithout at least 7 years work experience or hands on expeirience..
