Ask Mozart if playing the piano is hard.
Some people can do it, and some can't.
Some have a natural gift, and others have to work ten times as hard to achieve the same results.
I think the problem here is you're only looking at yourself, if you've reached this conclusion.
Something that is perceived as "easy" for you... so you think it must be the same exact experience for everyone else, because you represent "all people." It's not. And you don't.
That's true with everything, not just acting.
But acting is more than just tapping into your emotions and being able to communicate them effectively. That's fine if you always want to "play yourself."
If you want to be a versatile artist, you'll need to study or practice a variety of things from accents to movement, etc. You'll need to be able to research your characters, and study history and the history of human nature, not just throw on the costume and "behave." Again, this can come easy to some, or not.
But most of the really good actors I see are aware of life, not just self-aware. The more that actors become wrapped up in themselves the less they will have to pull from as artists, and the more limited they become in their work.
