The last thing I would request everyone to do is open a PPF account. Best the PF your office makes you save for, a PPF is the best for tax free returns too. You get returns which are not taxable and this makes this kind of investment the best! You have to put in a maximum of Rs 1.5 Lakh a year and a minimum of Rs 1000. I put at least Rs 30, 000 in it every year and shall keep doing so.
Try the above investment options for at least a year or two and you will feel what I feel. Who does not like a fulfilling, stress free sleep?
