Spending. That necessary evil. Spend too little and you could end up torturing yourself. Spend too much and it could burn a hole in your pocket. How much should you spend? Mumbai-based Bhaven Udeshi, 32, would not track his expenses. Before he got married in 2012, at the end of every month, his bank balance neared zero, despite a monthly salary of about Rs60,000. He ate out almost every weekend; or even twice or thrice a week. And it didn’t help that he did not have any investments; not even tax-saving ones. “I used to spend about Rs10,000 every month back then on just eating out and fine dining,” said Udeshi.
