How do you get to the back teeth?

I use an electric toothbrush and floss sticks. I
Like using the pointed end of the floss stick to make sure I get it all.

I guess I don't really, it's not form a lack of trying. If there is a trick for it I do not know it. I try my best to put the string between my thumbs and force it towards my back teeth. Trying my best to co ordinate myself.
