Question

what does it mean to \foul\ yourself when you are your own personal referee?
you call other people out on their problems.
you call yourself out when you make bad choices.
you allow yourself to break the rules occasionally.
you punish yourself for making mistakes.

Explanation:

When being one's own personal referee, "foul" refers to self - accountability. Calling others out (first option) is not self - refereeing. Allowing rule - breaking (third option) is the opposite of refereeing. Punishing (fourth option) is more extreme than just "calling out". Calling oneself out on bad choices aligns with the concept of self - refereeing.

Answer:

You call yourself out when you make bad choices.
