"If the answers to these questions are YES, there is no way you can fail."

I think this quote means that if people trust you by the way you never give up yourself. And also doing the right thing for yourself and choosing the right. And also the people that you treat them the people are going to treat the way you treat them.For example, if your parents let you go somewhere and they tell come at 7:35 and you do then your parents do trust on you. Another example, is that if choose the right you could have a good education and a your dream job or something.Also another example, is that if you treat your neighbor with respect then your neighbor is going to respect you back because they see that your a nice person.
