Never give advice unless asked.
I found everyone had opened the shop for advice. Most of the time people make you dull and sunshine less.
You have enough things to do in this life, why you are advising someone? what is the point? what are you adding to his life?
you have a right of concern. you believe in goodness. you like the betterment of the others. But it won’t allow you to advise.
you could be your judge and you could be your destination end. Your mother and your teacher can help you without any expectations.
