Learn a backflip

I have been trying to learn a backflip for so long now. I have watched tutorials on Youtube but nothings helps. I have also been contaction people who could do a backflip. Only one answered me and he said not to look back and instead try to stare at an object until i cannot see it anymore. I tried that but it just doesn't work. Normal people should be a able to learn it within a few weeks but i can't even learn it in month. Mabey im just not "normal". I'm hoping to find a backflip expert who could teach me to land. Here is a clip of me doing it.
