Thanks for the long reply, I do feel i could save a lot of money just tracking my purchases. The thing is i know i waste a lot of money on stupid things (e.g. fast food for lunch 2-3 times a week when the wife made a sandwich or several £2-£5 purchases on the many online games i frequent) and if i stopped doing that i could probably free up at least £100 a month.

My mindset is "I have the money, whats £5 for a little enjoyment", i suppose if everytime i thought that, took the money and put it in a jar, i'd be saving a load.

On the flip side ive recently gotten a new PC on finance which is going to be a £50/month expense, but thats something ive wanted for a good 2+ years and held off getting because to me it was a big commitment of money, its only now when regardless of my expenses we're being left with £500+ free at the end of the month ive decided to treat myself to it.

My wife is my weakness though, i sit there fretting over my PC but ive bought her an iphone 7, ugg boots and 2 Jimmy choo perfumes (£60~ish) in the last 2 months. heh, she's happy though!

tl;dr - youre right and i should really watch my finances.

You mentioned software, i think i'll look into that if it makes it easier.
