Reduce the small things (the triple foam latte rule)
This is a picture of the most expensive Starbucks drink ever: A 13 shot venti soy hazelnut vanilla cinnamon white mocha with extra white mocha and caramel. It cost a total of $13.76 (with tax).

This is clearly excessive - but the point is the same: we all are able to reduce daily costs in a minor way. They add up in a major way.
Maybe it's changing your venti latte to grande americano and saving $1.50 a day or brewing your coffee at home. I dont think you need to forgo coffee as there is a value on your happiness and if you consider it a meaningful part of your routine - then keep it but reduce the cost.
