In my life i'm poor, have no friend who I can truly trust and in my family I literally don't trust anyone, BUT I love my life without any doubt because I learned to love myself a long time ago, I have a big goal to strive for and my plan to accomplish it is already in practice. So for me the best standard of living is knowing yourself and then having a why so everything else is kinda of irrelevant and if you go further and make one self-fullfiling goal then you will be happy everyday
