‘How’ limits you to your own knowledge, experience and capabilities. It requires you to engage your time, energy and attention into a particular task that may or may not matter. Worse, ‘how’ decreases your freedom of time.
‘Who’, connects you with different knowledge, experiences and capabilities. ‘Who’ gets you desired results as effectively as possible. ‘Who’ immediately frees up hundreds of hours for you to put into stuff that really matters. Above all, ‘Who’ expands your vision for what’s possible, because you no longer see yourself as the sole entity of achieving the desired results.
