…i’m reading right now an interesting book - Essentialism. it beatifully demonstrates how to decide where it is worth to invest your time and energy. and it gives you great framework for doing just that.
another theory, you’ll say?
well, 37signals, builders of the great web apps announced they’ll… drop all other projects and focus on only one - Basecamp.
that’s how you put theory to practice. by the way - i highly recommend all of the 37signals books, they’re great source of proven advices how to build your own business and how to choose paths in life.
