One modern trick to earn a tiny bit of extra money: Use credit cards for buying/paying anything at all, never use debit cards or cash: Credit cards usually pay a small reward point for spends which can often be redeemed as a cash discount later, and also since the expenses go to the credit card, the cash in the savings account stay untouched till the day you make the credit card bill payment, which will keep earning interest for the additional days it remains in your account(Which may be a significant amount over long term, in a high interest rate country).
In some countries you can route large payments like insurance premium payments through the credit card. Sometimes insurance companies even have investment products which they claim are "insurance policies", that can be bought with credit cards too.
