It is very likely that you don’t have balls to build a high performing company. It requires remarkable drive, uber-focus on the business, audacious and inspiring leadership. It requires obsession with results, continuous sense of urgency, constantly challenging status quo, living the uncertainty at all times. It requires decision making which separates emotions from rationale, making every decision for the prosperity of the company and not you personal comfort. It also requires laying off mediocre employees, parting from co-founders, jeopardizing the future of your company and best co-workers. You must be relentless risk taker.
