My eyes are bigger than my stomach

The other day my wonderful, supportive husband gave me a lecture on over-extending myself. This may have had something to do with the fact that I currently have four books (two novels and two textbooks) in various stages of writing and editing. Or maybe it was because I had just announced to him that I intend to attend the GayRomLit retreat for the first time, even though that will mean traveling to Albuquerque less than two weeks after I return from a conference in Europe. My husband may have had a teeny-weeny little point.

Whenever I ordered more food than I could eat, my grandmother used to say that my eyes are bigger than my stomach. I wonder if there’s a similar phrase that can be applied to life in general?
