I first learned about design as a discipline in college. However, in retrospection, I've been practicing design since 5 years old. Back then, my grandpa, who was a heavy smoker, looked after me everyday. Knowing smoking is bad for health, I wanted my grandpa to quit smoking. I tried telling him to quit smoking, but it did not work. Hence, I knew I needed to come up with a creative solution. I noticed that my grandpa liked smoking while laying on his bed, so I drew a little face on paper, cut it out, and sticked it on the wall facing my grandpa's bed. In that way, whenever my grandpa smoked, he would see the face I drew with a pair of eyes "monitoring" him :)
