I Will Teach You To Be Rich
by Ramit Sethi
I Will Teach You To Be Rich, Ramit Sethi's 6-week personal finance program for 20-to-35-year-olds is based around the four pillars of personal finance--banking, saving, budgeting, and investing.
The book is great, as it focuses on increasing income, while still allowing yourself to get a "Starbucks coffee".
This book single-handedly helped me 2x my net worth.
I didn't quite like the "banking negotiations" part of the book
“The single most important factor to getting rich is getting started, not being the smartest person in the room.”
