"In any moment of decision, the best thing you can do is the right thing." - Theodore Roosevelt

This statement is telling us to do the right thing. For example if is someone is getting bullied and you don't know what to do about it your immediate reaction should be to do the right thing and stand up. You shouldn't just stand there and do nothing. Put yourself in their position. Wouldn't you want someone to stand up for you is you are getting bullied instead of the other person just watching. Another example is if you find money on the floor then you should return because it is the right thing to do. You shouldn't be contemplating weather or not you should give it back to the owner.
