If you have power to change one thing

It would be the society! change this lame society into a more disciplined one.

I will have a house ,a lot of money and a lot of beauty

if I have the power to change one thing, I would definitely go back in time and change all the messed up things that I have done in my life. I don't want to be a hypocrite and say that I would want to change the world without changing myself first. I had some troubles in my life and I definitely would make it better. Not easier, just better.
