I grew up with Shakespeare, and there are so many wonderful teachings in those plays. The stories are all so unique and timeless. There is just so much learning in that body of work, and that is something I will always go back to.
In my gap year between college and drama school, I taught art at a hospice and worked at a little coffee shop across the street from Shakespeare's Globe Theatre in London when everything around it was still a construction zone.
We work so hard as young artists to further our careers or improve our technique, sometimes it gets so easy to not actually go and see things like a play or a film. I think the best way to get better is to see other actors do what they do well.
