I am a grade 9 learner my talent is drawing but I wanna be a personal trainer but also I'm very lazy and I just don't know what to do. What do you think I should do??

if you are lazy then either

(a) you will never succeed at anything
(b) you will be very successful because you will try to find the easiest way to do anything.

discover what you love, and find out what it will take to succeed in that field. Talk to someone successful in that field.
