Save money by saving your change
The best mindset for saving is to respect every single dollar. Even coins represent value. Whenever you pay cash for something, save the change. Pay for a bottle of water with a $10 bill. Pay for an oil change with a C-note. Throw refunds and rebates into the mix as well.
Some personal finance apps, like Qapital and Acorns, will save the change for you. Qapital rounds up every purchase and deposits the difference in your savings account.
