Right. It helps to have aptitude for something in order to get good at it. Although that can depend. A person might have aptitude and never realize it because they had a bad teacher. When I was a kid, I was horrible at math. And maybe I still am. But I have to say, the last 2 instructors I've had have made it make more sense than at any other time in my life. I actually like math now. Granted it's only pre-algebra at the moment. Maybe once it gets more difficult I'll have a change of attitude. But the teachers I've had at the college I go to have made all the difference in the world. Then again, I'm also about 25+ years older now than I was the last time I took classes like that. So my brain is different now too. Lots of things factor in when learning stuff.
