So where have we all always been told to apply our blush to? The apples of our cheeks. We've been told to smile, and then apply blush to the fleshy part that juts out under our eyes right? Wrong actually.
You see, when you apply blush to that part of your face when you're smiling, it drops down your face as soon as you stop. The only time doing this will work for you is if you're always smiling (and that kinda hurts after a while).
So instead, smile first, to remind yourself of the area to apply blush to, then stop smiling and apply it to the skin that is there now, and blend up and out.
