"Always do right"-Mark Twain

 What this quote means is that to always choose the right. Never choose to do the wrong. When you choose the right you get better results and be successful in life. Also you will be very happy in life. If you choose the wrong you will be unhappy and never be successful in life. For example, if you choose the right and always do your homework then your teacher will have more confidence in you and you will also get more opportunities in life. If you choose the wrong however no one will trust you and or like you. You will have no opportunities in life and you will be very unsuccessful and miserable.
