252 LISTEN TO YOUR WISER SELF! Ever found yourself half way through the revolving doors, bent on buying some- thing you don't really need? Pause, and listen to what your wiser self has to say about it. He says " Wait! Remember: you pay your money, and take your choice, so why not wait till there's more choice in the shops. Be sensible and go on buying National Savings Certificates." Every 15/- Certificate earns you 5/6 in 10 years' time. This increase is not subject to Income Tax. BECAUSE They're easy to buy, easy to hold, easy to cash.
