It might be controversial whether DRIPing is going to sustain one to have an early retirement. Nevertheless, this book provides a good alternative for some simple long term investing for regular folks. The idea that impresses me most was not about how early the author got to early retirement, but his definition of retirement that was revealed in the book - not about having unlimited material possession or "n" million of money in the bank, but the humility and satisfaction of understanding what is enough. I like this book.
