Idiom Magic:一心多用致力不從心 Spread oneself thin

【明報專訊】Mr Potts is trying to do several things at the same time. If you ask me, I think he is spreading himself thin. I say that because to spread oneself thin is to do too many things at the same time. Maybe some people are successful at that, but in most instances scattering (分散) one's energy and skills leads to bad results. "You know as well as I do that you can't spread yourself thin and perform at your best," Mrs Potts suggested.
