Need a video that shows that without practicing easy thing may be hard and vice versa

I want to present a lecture on LaTeX to freshers. Many people guess that LaTeX learning is very hard. But, actually practice makes a thing easy. Without practicing a pilot can't ride a bicycle although a 6 years boy can ride the bicycle. So, on my presentation I want to show a video(funny or not) that shows that without practicing easy thing may be hard and vice versa.

Thank you.
