I remember when I was starting out my career, there was a lot of talk about living like a millionaire without spending a million. It was a very popular idea among sensible people who like living well but not spending a fortune.
My dad used to tell me, "You can live like a millionaire or actually be a millionaire...but not both." That was a broad generalization but I took it to heart.
I would amend that to say, "You can live like a millionaire but not spend a million doing it...if you are clever."
I think you will enjoy those books. :)
