Great idea six. Hope you don't mind if I follow your format 
Firstly, spent £10 yesterday on a taxi home from SIL's after a fabulous Christmas Day. Never been so chilled and relaxed. Slightly tipsy by the end of the day and after party games, but a lovely day. NSD today as we are going to my brothers.
Also started being frugal mid year, so still learning!
greatest achievements
Getting and keeping on top of the finances
Slashing the food budget, and stopping so many 'top up' shops.
must do better
getting to the week before pay day and thinking we a doing ok, so splurging.
planning for known expenses such as MOT's, tax, holidays etc, but hopefully my new method of splitting our wage will help.
favourite frugal habits
using money saving websites.
getting my fruit and vegetables delivered from the local market, brilliant for me,
bad habits
not being frugal when I should be!
DH not buying into the idea and going wild!!
M&S food shopping 
best bargains
walking into M&S when they had just reduced all their food and walking out with a trolley of food for a few quid.
Need a year for this topic I think!!
waste of money
the bloody pony
spending aspirations for 2015
being able to live from the paid monthly wage, rather than using DH's dividend, which is substantial to be fair and he's been in the position to pay one every year since he started, but isn't guaranteed income, and I need to stop thinking of it that way.
Agreed, new pillows, duvets etc. Ours are ancient and dreadful.
Having 'pots' of money for everything, even if notional.
