So on some page they suggested that it’s a good idea to keep track of the money you spend in a month. So I’m going to give it a go:

Day one
Gym membership – £40 (essential)
Barclaycard payment – £91.71 (essential)
Food shopping – £10.32 (essential)
Hair cut – £14.50 (essential)

Running total – £156.53 (156.53 essential – 100%)

Worrying start!
