Credit is sort of like a sharp knife. Handled well it can be a very useful tool, handled poorly it can be a great danger.
I think I can honestly say that I have been through both types of debt. Right now, thankfully, I am well on my way to using credit as a tool. Before Mrs. MediaBlog and I got married, both of us were pretty heavily in debt... Credit cards mainly. Now, after a lot of struggle and some sacrifice, we're almost out of it.
