Owed about $2,000 to my parents for the car I bought from them in 2009. Then, in 2010, I owed about $2,000 to Ford for the Focus I bought from them to replace the one a Charger totalled. (The rest of that car's price was covered by the insurance check. Full coverage, FTW.) Now, I'm debt-free, and intend not to owe money to anyone again.
Right now, I make $1,300 per month, after taxes, and spend about $800 - $900. If I find myself making $13,000 per month, I'll probably still endeavor to live on about $800 - $900 each month, so that I don't need to worry about a mortage or car loan in the future. Save, save, save. Good things come to those who wait (and save). Save early; save continuously. Et cetera.
