Brain Helps or Devotion Helps ?

well the brain helps...but for me i think devotion is more important. i failed a cl 3 times before i ped it, but i refusedd to quit. my brain didnt want to learn the material...but im motivated to have a career so i studied a lot (which really sucks when the subject is something u hate and dont understand) but i did it! point being, dont let anyone tell u that u cant do something, or you arent smart enough. you just might have to work a little harder.
