What mistakes do people commonly make with money while planning retirement?

The common mistake that people make with money is that they pick a random retirement number (₹1 crore, ₹5 crore) and consider it enough, as per Moneycontrol. Ignoring inflation and healthcare expenses are other mistakes that people make. According to Moneycontrol, becoming conservative (moving everything in cash or fixed-income deposits) can create problems if retirement lasts several decades.
