"Ask yourself is it right or wrong and act accordingly." 

This is trying to tell us to think before we act. It is like how we have to think before we speak or say. Don't just act without thinking because bad things can come from it. For example if your mom tells you to be home by 5:00 and you decide to go home at 8:00 you are not thinking correctly. Because your mom is telling you to be home at specific time and your aren't obeying her then it will lead to serious consequences. So don't choose the wrong. Always choose the right and good things will happen to you. If you are not accordingly then make sure you are asking yourself am I doing something right. Or am I just trying to impress other. Asking yourself what you are doing and think twice. Therefore you should always choose the right because it benefit you in a good way.
