Nikhil Kamath, the co-founder of Zerodha and one of India's youngest billionaires, recently opened up about the passage of time in an emotional Instagram post. Addressing MBA students, he reflected on how quickly life moves, stating, 'Where did my youth go?' This sentiment resonated with many, as he acknowledged the bittersweet nature of aging while being called 'sir' by younger students. Kamath's journey from a middle-class Indian household to a billionaire entrepreneur is well-known; he dropped out of school at 14 and founded Zerodha, which has transformed India's financial markets with its innovative, low-cost brokerage services. Beyond his business ventures, he is committed to empowering young entrepreneurs through initiatives like the WTFund, launched in April 2023, which provides grants to individuals aged 25 and under. Kamath's philosophy emphasizes the need for nurturing entrepreneurial skills and supporting ventures that address real-world problems. His reflections serve as a poignant reminder of the fleeting nature of youth and the importance of making a meaningful impact.
