1. High confidence level and expectation
When a person has too high confidence level is not good at all sometimes, for example when you're too overconfident over something. In the end, the result is not up to your standard / expectation you will feel very down and sometimes may also feel demoralised and you will also feel that this is unfair and you don't deserve this type of result. Whereas, a person with not too high confidence level is a good thing most of the time so that when you know the result and it's not up to your standard at least you won't feel too hard and down compared to a person with high confidence level and expectation. Don't set too high expectations for yourself if you cannot meet the target, set a target that is appropriate so that you won't hurt yourself too. Having a low confidence level is bad as you will forever have no confidence with yourself and think that you will never accomplish the thing.
2. People who love correcting others
Here is to me people who love to correct others. People that love to correct other's way of pronunciation and claim that there's pronunciation is way better than yours. Everyone have their own ways of pronouncing words and no one is perfect in pronouncing words and if you have a perfect way of pronouncing go be a teacher instead.
