If you ever think life is too boring and want a real challenge, or if you find life difficult and want more challenges so you have to organize all of your life by the minute, then just get cast in an independently produced film based on an obscure Shakespeare play that uses the original script. You'll quickly discover that memorizing Shakespeare is not like memorizing other lines. It's harder. Especially if you have some long scenes.
So challenge yourself. It helps prevent Alzheimer's disease. Or dementia. Something like that.
