“Ask yourself is it right or wrong and act accordingly.”

This quote is saying that you should think about what you are going to do first then you go ahead and do it. If you don't think about what you are going to do whether it's right or wrong you shouldn’t do it because you don't know how it will turn out. You should know what to do before you actually do it that way you know how it's going to function. For example if you want to look for a job but you don’t know what do have or do when your going to interviews or filling out applications, you're not going to get what you want. You have to know and be prepared for what you are going to do. If something you want to do is bad you shouldn’t do it even if you have to. If you do it your actions wouldn’t turn out good and you will have to suffer consequences. If you want to do something good you should do it and do it the right way. People like to do stuff without thinking about what is going to happen. If you want something to turn out good then find a way to do it the right way.
