If you could instantly master any skill, what would it be and why?

I like to draw and pain images during my childhood days. I draw and paint images as a hobby in my childhood days. I draw and paint images when I have free time from studies during my childhood days. But when I reached high school then I was busy in preparing high board exams and later intermediate board exams. So I was busy in studies and not have time to draw and paint images.

I was continuously busy in preparing competitive exams, completing graduation and later job so I have not time for drawing and painting images.

Thus, If I could instantly master any skill then it would be drawing and painting images because I like to draw and paint images during my childhood days.
