"Tell the Cohens I can't make it for dinner tonight because I have an
important meeting, so we'll go out on Thursday. Then call Mrs. Smith, and
tell her that I am too busy this Thursday to do my weekly volunteer work
with her autistic son."
"And he (Bilaam) saddled his donkey (on his way to cursing the
Jews)" (Bimidbar 22:21). Rashi points out that in order to do an evil
act, Bilaam was willing to saddle his own donkey, which was really beneath
his dignity.
Use your mundane acts (or sins) as a yardstick to see if you really can't do
that mitzva!!
