"Eat That Frog! 21 Great Ways to Stop Procrastinating and Get More Done in Less Time" by Brian Tracy is an absolute goldmine of a book. Without question, this is a 5-star book.
Before you read it though, it's important for you to understand what it is and what it isn't.
It's not a deep-dive treatise of productivity systems; rather, it's an overview of the core principles of productivity that you need in order to organize your life around accomplishing more, meaningful things that will move you toward your goals.
It's short, fast, and pithy.
Tracy begins with the big picture focus of making sure you're doing the right things--planning the things to do that directly tie to your goals and things that are going to have the biggest impact on your achievement of those goals. Then he continues with the practical suggestions to help you actually do those things.
Here's my recommendation: get the audiobook version and listen to it on the first of every month for the next 60 months. 
Even if you did nothing else for your personal development and improvement it would be enough to catapult you into the upper tiers of your company and career. 
Enjoy!
