I got this from the Post A Day blog.
I’ve read, for years, that there is good debt and bad debt. Good debt has been defined as the debt one incurs to earn more money (investing in a business, education, etc) and bad debt is debt incurred on depreciating assets (like cars) or in a high interest situation (credit cards). When I was a kid, my dad was big on letting me know that all debt is bad debt. Does anybody still believe in good debt and bad debt? I know I’m leaning hard towards my dad’s view on debt.

I am terrified of debt and have a hard time believing that any debt is good. You’re fortunate that your dad taught you about it early. I don’t even think I heard the word until I was an adult and experiencing it for myself. Which explains my fear of it now. Been there and done that and will NEVER do it again.
There is nothing like having experience for a teacher. I’ve learned some money lessons through experience that have me in the same mode as you are.
