I think I am. We all have a tendency to spend money easily. In my business I get paid every 1-3 months for my services, hence the credit card comes in handy, and it is linked to my house. I've just paid it off - yay! Even on a six figure income, I think I am careful with my cash. Like everyone, I have expenses to match that high income, especially as I am putting as much of my income as I can into my mortgage on my house to kill it fast!
