When it comes to Financial Products, it is more important to know what not to buy rather than what to buy. One simple thumb rule is, whenever you buy any insurance/investment product, you should do mental mapping of it to meet your family’s financial needs in future. Those needs include children’s education, retirement, health-care, disablement etc. If you can’t map it to any need, but if you still buy it for other reasons like saving taxes, you will be committing a mistake. Few such mistakes can cost you peace of mind in future as you will end up in fire-fighting to meet your needs then!
