My family has a bad temper, so do my parents, grandparents and even grandparents. So did my brother, so I inherited it naturally.

It can be said that temper is innate, but it is actually acquired temperament, and the proportion of hereditary personality factors is very small. Now, whether it is genetic or acquired, it has already formed a fact, which cannot be completely changed, but it does not mean that it will never change. Everyone is going through a stage from immaturity to maturity. The so-called maturity means that you have experienced many things and have been ground to no edges and corners. Specifically, they can hide their temper without getting angry or showing it casually. They will only be hidden and can only be suppressed. Now it can be concluded that you are still in an immature transitional stage, and gradually you will become pessimistic. Will you care about something casually, will it get deeper, but it will take time, and you will definitely not get angry casually like this.
