> is a personal choice

It is, in the sense, that your personality determines it. But you can't determine your personality. If you are born curious and independent, you'll probably find your way. You cannot chose your genes. This thing about immediate gratification is a lot about genes and environment. If you are born in an environment where only instant gratification is valued, and if you don't get the right genes, there is no chance, you can change your life by yourself.
