More due to my mindset changing in the past weeks from thinking wouldn’t it be amazing to do the extension we always wanted or to move to the house we really like or to buy that nicer car or go on the honeymoon that we never got round to,
To wondering if we need or want any of it
This is what I think. £100K in "fun money" totally imaginary terms is different to the reality of it, if you've already got some "wealth" (e.g. a house with a mortgage, for most people).
In "fun money" imaginary terms, I'd sort out the house layout and get a new kitchen, bathroom, carpeting, landscape the garden, have some amazing holidays and put some by for new cars, and then pay a little off the mortgage to "be sensible".
In real-world terms, I'd pay almost all of it off the mortgage, not feel any better off short-term, and maybe have a holiday.
Being sensible with money sucks.
