Acting

Acting is an art form that has always been looked down upon
a lot of people come out of the theater saying degrading things like
"That actress/actor was so bad, I can do so much better!"
"You call that acting, if i was an actor I'd probably won 6 Oscars by now."

well acting isnt as simple as it sounds or looks.
acting is similar to painting a canvas and winning an Oscar for Best Actor/Actress
means you have painted Mona Lisa or Sistine Chapel

in painting, the painter gets a subject to pain and use different brush strokes and styles to paint that image

in acting the subject is the script and screenplay
once the actor/actress has read the written words, he or she must translate them into motion and emotion (getting a brush, paint, and canvas and painting the image)
next the actor/actress on stage or in front of cameras improvise (adding their own style and using techniques)

u also have to keep in mind that when these actors and actresses act, they are creating something new they are translating words to body movements and emotions
When we watch a movie, tv show, or a play of course it looks easy, we have observed how the actors react in certain scenes, we have obtained the basic idea of how actors act
we imitate what the actor has created nothing more.

this concept goes for all art form just in different form
so next time you want to say "I can do better." after you seen a movie, play, or TV show think about what carefully you say
