Can i make it to the NBA?

I'm 18,i just started working two months ago. I have a 3.2 gpa in high school right now,and i am fairly religious. But,i realize that i am smart,but lazy. I really don't take consideration or interest in certain things or anything but basketball...i acknowledge my parents,but i wouldn't say the word "love". I'm 6'1 andi have a 6'6 wingspan yet i have never played in high school. What should i do and how can i make my dreams a reality to play in the NBA? Also,i'm a very shy person and i have tiny hints of introvert-ness.
