I used to not use credit cards for much of anything, except ordering stuff. But over time I started using them for everything. There just wasn't a good reason not to and that lack of reason not to on the one side was balanced against meaningful benefits on the other. So now I use credit cards pretty much everywhere, except at fast food places or in convenience stores or in situations where you kinda have to use cash. Every now and then I won't use a credit card because I realize that those few bucks might make a difference to the person I'm doing business with, so I give them cash to save them the processing charges - that would typically be for a larger purchase though.^ This^ Except, I rarely charge that much in a month.
WR, I recommend a budget. I have had a budget for years and I stick to it. Budget EVERYthing...savings, too.
