The sleeping groove is too hardcore! Business tycoon Kevin O'Leary directly opened up the absolute trump card that Jobs and Musk could crush ordinary people. He recalled his experience working for Steve Jobs in the 1990s during the interview. When he proposed spending millions of dollars on market research to see what students and parents really want, Jobs mercilessly retorted: I don't care what they want, it's me who tells them what they should want. Behind this extreme tyranny lies an efficiency rule that all top entrepreneurs are stubbornly adhering to - the 'Signal to Noise Ratio'. What exactly is a 'signal'? It is not a vague long-term vision, but 3 to 5 core tasks that you must relentlessly pursue and absolutely complete in the next 18 hours of wakefulness. Except for these few things, anything else that attempts to distract you - whether it's ineffective socializing, social skills, or meaningless phone browsing - is all "noise" that must be ruthlessly cut off. Steve Jobs was able to achieve a terrifying signal-to-noise ratio of 80/20, while Musk is an extreme monster. O'Leary bluntly stated that Musk's brain contains almost 100% absolute signals, without any noise, even if it makes him appear extremely strange in real social situations. Even Bezos refused to make any core decisions after 1 pm in order to avoid the interference of noise. In this era full of information garbage, if your energy allocation cannot even achieve a 50/50 signal-to-noise ratio, you are destined to become cannon fodder in the business world. The ultimate focus and absolute cold-blooded noise shielding power are the core moats that cross social classes.
