⟩ Why should you not neglect any minor criticisms you were given?
A positive performance review does not necessarily have to be 100% positive. Take note of any criticisms you do receive during your review and give them the same amount of attention you would give the criticisms from a negative review. Supervisors love employees who are not satisfied with "good enough", so look for opportunities to go the extra mile and earn a 100% positive review next time.
☛ In addition, it is worth remembering that, at your next review, your supervisor will probably bring up these past criticisms. It can be very embarrassing to explain to your supervisor that you have not taken any action based on these criticisms, so do not put yourself in this position.
