Given our humanness, we are prone to making judgments on things. Well, everything actually.

Good vs. bad, hot vs. cold, right vs. wrong, etc.

These judgment calls are almost always based on past experience--our past actions/feelings/understandings are naturally going to shape the way we view the world today, and thus, the way we feel about everything.

But these dichotomies of right and wrong are made up in the mind. Things are not one way or another, they just are. And no matter how you view anything, there is always going to be someone who views it exactly the opposite as you. For example, Nebraska summers--brutally hot, right? so easy to complain about because of the discomfort they cause. However, talk to a Nebraska farmer and he/she will tell you the necessity of the heat to grow corn. For them, the heat is a good thing.

Through a yoga practice, we can start to cultivate the awareness of things just simply as they are. Try spending an hour without judging anything. It's nearly impossible. And the nature of our labeling is often a misunderstanding of the true essence of that thing. In the 1978 translation by Sri Swami Satchinananda, Verse 1.8 of the Yoga Sutras states

Misconception occurs when knowledge of something is not based upon its true form.

How do we start to change? Part of the practice of fully understanding something is often a matter of a shift in perspective--a regularly occurring theme of this blog! For instance, moderate suffering can be a reminder of the things we have to be grateful for. Another example, if a new teacher shows up to teach your yoga class you may be dismayed because of your attachment to your teacher, or you could consider that you may learn a new pose or hear something cued in a way that resonates with you.
In other words, get the full story. And try to keep in mind that no matter how you label anything, there is always another way. And that way isn't necessarily wrong. It just is.
