Criticism
Something no one likes, we all wish we could do without, but most of us benefit from in the end: criticism. In your time in school or work, I am sure you’ve had to go through peer review or peer edits, it’s inevitable. We use criticism to help evaluate our shortcomings and our talents to see what we can hone and what we can improve.
Hypocrisy
Everyone is looking at how people dress, talk, what they do for a living, and any qualifier you think of. Imagine how hard it would be to force everyone to dress how you’d like, talk how you’d like, and do what you’d like. You’ll find most people would rather keep to their own standards and march to their own beat. This is why you’ll always have hypocrites: everyone thinks that their worldview is the only view that matters.
Judgement II
People love to judge but hate to be judged. Being judged is inherently an uncomfortable process by which are weighed, willingly or not, and found wanting. It’s a subconscious act, to look at someone and measure up their worth. One of the overwhelming problems with that stems from how we use our own criteria. We are not fit, being inherently flawed, to judge the merit of others.
