I allow myself only to use specific amount per week/month. If said amount is €1000
If by the end of the month I manage to save €200, instead of depositing €1000, I deposit €800 and €200 goes into savings.
I have multiple bank accounts for this purpose.
Cut all expenses you don't need.
But again, try not to live in utter poverty. Life has to be enjoyed, but for the time being at least .. depends on your age... try to find another source of cash.
