Four thousand weeks

Four Thousand Weeks: Time Management for Mortals by Oliver Burkeman is a book that highlights how humans miss the forest for the woods, by focusing on things in life that aren't impactful.

The average human life is 4000 weeks or 96000 hours. Your time on work should be spent on things that have the most impact on your life. Spending time doing mundane work robs you of the opportunity to run an exceptional business and lead a fulfilling life. In spite of fact that we may train ourselves to become more efficient at doing tasks. All we do is move from task to task.

We focus on the how rather than the why; this is the reason why, as a solopreneur or a small company, we try to wear multiple hats and hence spend most of the time performing tasks—essentially work in the business rather than on it—and as no one can be really good at a lot of things in one lifetime, small businesses end up never coming out of this vicious circle of needing to grow profitably but not having the time bandwidth or resources to hire talented and motivated people to help them scale.
