Should my diversified money try to beat the market, or just track it?

For money that is your safety net, the honest answer is usually: do not try to be clever. You already carry enormous concentrated risk in your startup, so the diversified part of your wealth is meant to be the calm, boring counterweight, not a second bet. Most people, including professionals, do not reliably beat a low-cost, broad market index over the long run, and trying often means higher fees and more mistakes. Tracking the market with simple index or diversified funds is easier to stick with and lets you spend your energy on the business, which is where your real edge is. JL Collins' stock series and Bogleheads make the case for simple index investing, and Zerodha Varsity's mutual funds module explains how funds work in India. Past returns do not predict future ones and tax rules change, so treat this as general education, not advice, and confirm specifics with a qualified advisor.
