Startup is a game of speed, but also a game of wait.
As a CEO, most of my time goes in waiting. Waiting for a new version to be developed, waiting for the right investor, waiting for their yes, waiting for a business model to work, waiting for the right hire for the team and waiting for an app to go live. It is a tight balance between speed and wait. As a CEO, one achieves speed by being decisive, by having faith in one's ideas to outweigh the wait that is going to arrive during the process of building, testing and shipping, during the process of building the company with many variables outside one's hand. One part runs on impatience, the other on patience.
Donning the CEO shoe helps one evolve from being impatiently patient to becoming patiently impatient.
