Rav Yosef Yoizel Horowitz, the Alter of Novardok
“A man cannot dance at two chassunas (weddings).”
Meaning, you simple cannot be at two places at once. If you are at home with your family, then that you be your focus. If you are at work, then concentrate on work. If you are in shul for davening, then that is where your focus should be.
