Color your life and goals with self-awareness. There are no books and guides to provide you a better idea about this fact as you have to experiment and know much in detail about thyself. This self-awareness will give the quick start for your successful journey. So spend some time daily to know yourself in depth. This may not be easy but can be achieved with some practice which you can learn here.
You may not and can’t change yourself completely but for sure can try to implement some positive changes after getting self-awareness.
