Have you done a mitzvah today? A mitzvah is a good deed, something done to benefit someone else without any selfish motives attached to it. It is doing a favor without expecting anything in return. It is doing a good deed even if no one ever knows that we have done a good deed. In other words, we are not looking for the credit for doing this noble deed.

A get is a divorce under halacha, or Jewish law.  The word can also refer to the document that grants the get, though its technical name is sefer k'ritot, or scroll of severance.  The sefer k'ritot is a no-fault document, not citing any specific reasons for the divorce, though a sofer or scribe writes it out specifically for the couple involved.
