- you consolidate your finances in the minimum number of accounts & cards
- you have a couple of months of expenses as cash in a current or savings account
- you pay off your credit card in full every month
- you invest some amount every month
- all of this is automated - paying bills, credit card repayments, investing, putting money in savings, all of it.
Once you have these things down, you can then adjust percentages, providers and all other details according to your personal situation and preferences.
