Take a fruit in your hands, any fruit, whether it's an orange, a banana or even a walnut, try to cut them open, andwhat you'll see come out from inside is its pulp, juice and anything that belongs to the respective fruit or nut. Thereason? Because that's what's really inside and nothing else.
Now we use this principle on you, when someone rubs you the wrong way,you'll probably react,and what would come out from you is what's really inside.
If what's inside isrotten,then change it by improving your thought process.
