As a teacher I can say that in every class- adults or teenagers- there will be 5-10% who will love you no matter what, 5-10% who will dislike you no matter what, and everyone else will be in between.

You have to learn not to take it personally because it isn't; you're just the body in the room when they happen to be feeling shitty about their day, their life, their job etc.

Also remember that some people will just tick 10/10 in every category because they can't be bothered to do it properly, so don't let that go to your head either.

What you need to do is reduce it to pure numbers. Weight loss, for example, is not about how you feel or even how you look; only the scales will tell you the complete and accurate results without bias.

What you can measure, you can manage. Look at average scores over time across multiple categories. Is there a trend? If it's negative, then write up a plan to fix it. If it's positive, write up how you achieved it. Then show it to your boss and get a raise.

At the end of the day the shitty commenters want you to think about them. I usually just laugh; there's always one in every group.
