Acquiring knowledge is easy, but applying it in real life is where the true challenge lies, according to a new post by the entrepreneur and investor Naval Ravikant.

“Acquiring knowledge is easy, the hard part is knowing what to apply and when,” Ravikant wrote in a post on X on Tuesday. “That’s why all true learning is ‘on the job.’ Life is lived in the arena.”

The statement reflects Ravikant’s recurring themes of experiential learning and self-reliance, emphasizing that intellectual accumulation is not enough without practice and discernment.

Ravikant is best known as the founder of AngelList and as an influential thinker in the tech and startup worlds. He frequently shares ideas about wealth, happiness, and personal growth with his 2 million followers on X.
