The Automatic Millionaire - This book is almost embarassingly simple but it is definitely consistent with GTD principles. The whole premise is to pay yourself first. I found that I was so hung up at the runway level with finances - all the budgeting and quicken input that I was always behind in. It was a lot of work with little results at the higher levels.
This book is so simple and it gives an incredibly practical and sustainable method to get rich. I have implemented several things over the past 6 weeks - it's all on autopilot and taking full advantage of the things that matter most in having a financially secure and abundant life.
I had to get over the simplicity and look at the gap between common sense and what was common practice for me.
I like this book:
