No one is born to change their bad habits right away. First of all you can't think of yourself as too pessimistic. Think optimistically about everything. For example, when others say you, you can then take it as a kind of test for you, take it as a kind of test for you from heaven. It's just a word from someone else, but if you give in a step then it becomes a good thing for you to pass the test, so what do you have to be angry about? The sutra is a Buddhist scripture, but you recite it from time to time, but you don't try to y understand the meaning of its existence. When you are angry, try smiling. There is nothing you can't do if you have the heart. If you don't understand it you can always come and ask me, I am also practicing it constantly! You can also practice yoga.
