I will be sharing notes from this book daily for a week:
"Organise your professional life rigorously around your circle of competence. This radical focus will bear more than monetary fruits. Above all you’ll save time, because you won’t keep having to decide where to direct your attention. Knowing your circle of competence is your tool, your scalpel, enabling you to divide sources of information into what’s valuable and what’s not."
