trade off

last night i knew that my cousin bought a guitar and had a conflict w/ his parents n he's kinda gonna give up high school cert (the exam to university). looking back on myself. I've been saying that i'll learn guitar for 2 yrs yet i haven't done so bcoz i m too busy w/ school n church. it's just so hilarious that my cousin will give up his studies for guitar BUT i m giving up my guitar for the sake of studies! is this generation gap? 10 yrs could make such a difference? or it's just maturity?
