The Success Principles
I first read this book about 10 years ago and have re-read it twice since. The Success Principles is definitely a book to help you achieve your goals; personally and professionally.
The chapters are small and make a large book easy to absorb and then actually put the different strategies into practice. The second time I read the book, I did it as part of a mastermind group with two friends which was a very effective way to gain even more insight. We also held each other accountable to the goals we set as we moved through the book.
I highly recommend this book for ANYONE that wants to become more successful!
