Thanks for the positive and inspiring post 😀
I wanted to add that what can help hugely with saving is enjoying saving, or trying to. To this end I like the wealth app Chip - it's so easy to use, and I like the feature.
I also have some small funds saved in Premium Bonds, but not won anything yet. It's like doing the lottery every month, but you don't lose the money you've 'played' with.
Also - limit the fun stuff. E.g. If you eat out twice a month, do it once a month, or every six weeks.
Christmas? Forget gifting to others, your loved ones will understand why saving money is more important than spending money on gifts (I realise this is pretty much impossible with kids!).
If you want subscriptions (aka the new direct debits), rotate them. The companies love the subscription models because they know many people are too lazy or forgetful to rotate or cancel and want the consistent income.
