Sam Altman suggests that instead of searching for a perfect job, people should pay attention to how different kinds of work make them feel. His quote states: “If you can't figure out what kind of work you like, pay attention to what's easy to concentrate on and gives you energy vs. what makes you tune out and feel tired.” Altman advises using attention and energy as practical signals, noting that tasks which consistently make time pass quickly or leave someone feeling mentally refreshed may indicate a good fit, while work causing distraction or exhaustion reveals an equally important truth. He distinguishes between effort that feels worthwhile and effort that feels permanently draining. Altman, an American entrepreneur, investor and technology executive who first became widely known as the president of the startup accelerator Y Combinator and later became the chief executive of OpenAI, bases his advice on observing behaviour rather than abstract ideas about success.
