A strong lesson from this book is that no matter how small your income is, 10% of it is yours to keep. Grow your purse to fattening.
This book is highly practical and the lessons in them are capable of growing anyone's purse if applied.
I literally recommended this book to everyone I know especially those I sincerely want to see doing exploits financially.
In all, it's a great book. You should find out for yourself.
