Set a Goal to Reduce Spending
Setting goals can be a powerful motivator. Having a target dollar amount in mind to reduce spending per month will make it easier to cut items from your budget.
For example, if you decide you need to reduce your spending by $500 per month and you are currently running a billboard advertisement that costs about this much, it makes it a clear choice to cancel this advertising. Advertising is needed, but not an essential part of your business operational costs. Canceling something like a billboard ad may make you seek more creative or free methods of advertising that you find actually work better.
