Benjamin Franklin said "An investment in knowledge pays the best interest", meaning that gaining knowledge has long-lasting benefits. Investing in education leads to better jobs, higher pay, and a better quality of life. Knowledge also fosters personal growth by enhancing decision-making, problem-solving, and understanding of the world, leading to fulfillment that can't be measured by money alone. Continuous learning through self-directed study and technology allows updating skills and adapting to constant change, further paying interest on investing in knowledge over a lifetime.
