Got crazy in the kitchen today and practiced some acting. Wanted to see what you have to do so that your acting is natural. Tried 3 things:
1. Controlling your voice
2. Creating the feeling and then expressing it consciously
3. Creating the feeling and then letting it out... unconsciously/subconsciously, whatever
1 sucked big time, 2 sounded fake, 3 was perfectly natural.
Realized that it works the same for almost everything else in life.
