I have a bad temper because I am too self-righteous and always think that some of my ideas and practices are right. If others go against their wishes, they will feel particularly uncomfortable, anxious and unhappy.
In order to avoid losing control over trifles, I will write reminders on my mobile phone, wallet and all my personal belongings, such as: calm down and think twice before you act.
Read some books often to make yourself more sensible, tolerant and patient. At the same time, family ties are also very important. Whenever you lose your temper, think about the consequences, think about the harm that your favorite family will get, and try to restrain yourself.
It is not impossible to change your bad temper. As long as you have patience, perseverance and determination, you can certainly change according to the above methods.
