FU money is just the state of financial/professional security that allows you not to depend on your particular job. As previously mentioned, having a dual-income situation can make almost any level of savings an FU money situation. What also lowers the bar drastically is having a career where you can easily switch jobs (or careers). From this book, you'll get:

An idea of what you were put on this earth to do.

Increased happiness, purpose, and meaning.

A practical plan to future-proof your career.

A way to declutter your life, so you're able to see and think again.

A fully costed route to financial independence (call it early retirement if you like).

A system to manage your finances.

An investing plan that will knock your socks off and explain how you can get your F.U. Money.

If you read this book and carry out its recommendations, within a year, you will have transformed your future. It's never too late. Carpe diem. You are the master of your fate: you (and no one else) are the captain of your soul.
