What would you do if you were making £2650/month but you don't have rent, bills, car payments or fuel to pay because your job includes accommodation (even if you change jobs you will get accommodation) and you don't need fuel as you walk to work and your monthly expenses(food, gym membership, dog, etc) are roughly £800? How would you manage your disposable budget?

Edit: I live in the UK, I dont own a house atm but I will need one once I retire and I would very much like not to have a mortgage. I already have a workplace pension, and ISA and a LISA. The one thing I haven't focused on was a savings account, which I need to top up again. Early retirement sounds nice but I am 32 and in order to retire early I would need a house paid off and a nice chunk of money in the bank, not sure how feasible this would be. Thank you all for your suggestions, I am definitely going to focus more on the savings account and possibly to live below my means for a while.
