As I've written before, it's very important to not allow yourself to become overwhelmed. It is simply not healthy, and when you feel overwhelmed, you're not able to accomplish as much as you could if you sort out one thing at a time. As an actor, we live a lifestyle that has a lack of "structure." It's part of in our career. While it can be very exciting, this can also lead to feelings of being overwhelmed, as there is SO much to do!
The same may be true for many of you as well, in your careers and in your lives. When you do begin to feel overwhelmed, take a step back, and just relax. Remind yourself to take everything in life one day at a time, (<--- that's an article I wrote for acting.about.com!) and don't stress.
Life is too short!! Enjoy your day, and don't allow yourself to become stressed out! :) x
