If we become what we do and we do what we think, then if we ought to become something we ought to think more along the lines what we ought to become.
To put it more simply: if we want to acquire a quality, we should also improve the quality of our thoughts.
Better outcomes rarely come by coincidence, therefore studying others who have already achieved what you want to achieve is a good place to start. More specifically it could be useful not only study those who have achieved what we want, but also to study their ways of thinking, their thought processes to understand what exactly they are thinking with actions they are taking.
Deeper understanding opens up the ways of thinking, and therefore the ways of becoming.
