Was it a bad day, or was it a bad 5 minutes you milked all day?
Was your day running smooth and little Suzie made a rude comment towards you? Did you not get a A- instead of a B+ on your mid term? Stop letting one thing bother you for the remaining hours of the day and overcome that mishap. If you let the tiny things bother you and drag the negative shit with you all day, you’ll never be successful.
