That looks like the lists that my dad writes out every time he sees me smoke! You could've bought a villa in Spain by now if you'd never smoked!
Im looking at it in the same vain. My mortgage looks like its going to be between 650/750 a month depending on what I buy. If I don't smoke ill be saving roughly 220 quid a month on ****, plus all the other money ill save not buying all the other junk you do when you go in for **** like fizzy pop and sweets. I reckon I'll be saving nearer 300 quid a month. And that's a hefty chunk of my mortgage.
