I spent 25 years working as a professional engineer. Over that time, my wife and I saved and invested our money until we amassed enough wealth to become financially independent and retired in our 40s. I have written three books on personal finance. The common topic is early retirement. Each book is written for a different demographic. My most recent book, Wealth Hacks on FIRE (Financial Independence Retire Early) is geared towards people aged 30 to 50 who are in the workforce and desire to become financially independent so they can choose to retire early on their own terms. My book contains many non-mainstream approaches to FIRE. After all, the will to FIRE is non-mainstream so people with the desire to FIRE are already dissatisfied with traditional investment thinking, structure and timelines. I am confident that if you employ the tools presented in this book, you will find yourself in a much better financial position. My books are also available on my website arrivedeh.com
