Mia saves money by eating the same 50p breakfast of an eg and half a bagel (pictured) every day, avoiding buying coffee when she's out and never getting her nails done.
Mia, who is currently investing around £1,500 per month, realises that she will need to invest at least £2,000 per month if she is going to be able to pay herself £35,000 a year from the age of 40.
Elsewhere, Mia, who saves money on rent by living at home and buys second-hand clothes, explained that her side hustles include making content for social media platforms and modelling.
A fourth TikTok found it hard to accept Mia's choices, writing: 'I'd rather live now, I'll never understand this mindset.'.
A 24-year-old woman bent on retiring by the age of 40 has revealed how she has already managed to save £75,000 - but critics say she's missing out on her youth and 'should live in the moment'.
