the older u get the less time ur going to have to practice, so get good wen ur young and u wont need to practice as much wen ur older(speaking in lp POV)
evry1 thinks there no going to quite, but wen u have a full time job, u dont choose to quit, u eventually stop becoz there no time for hours of freestyling. i have no idea how the older guys do it, but u have to have given up somthing if u want to freestyle for hours a week.
so for me, i wont quit, ill eventually stop.
