When actors get together to rehearse their scenes, there is often at least one person (it used to be me) who couldn’t resist critiquing how well (or not well) everyone else is doing with their lines. The experience is a lot like trying to drive a bus from the back seat, frustrating and pointless.
The saying “Keep your eyes on your own page” is about putting your attention and intention only on the lines (or work) assigned to you, and anything that isn’t on your page is none of your business. Why? Well, basically it comes down to what is our responsibility and what we can control. If I am focused on what everyone else isn’t doing well (or what they are doing better than me), then I am not putting my attention on my own work. Even if I am right about what other people should be doing with their lines (or work), it doesn’t mean that anyone benefits from it. Only my ego, which loves to compare and contrast itself to others, gets something out of looking at other people’s work.
This may seem obvious to most people, but it is amazing how many of us still fall into this trap. If you are feeling frustrated with the work that others are doing, ask yourself if it is your business? Are you keeping your eyes on your own page? Are you doing the best work that you can do with the tasks that were given you?
My guess is that, if we are honest with ourselves, we will recognize that everyone is in a process, and the only way to contribute positively is to focus on our own work and leave everyone else to theirs.
In other words, the bus ride is a lot less stressful if we let the driver do her job, just as rehearsal are a lot more fun and work takes up a lot less space in our heads if we just let go and focus on our own stuff.
