Been debt free since the late 90's. Its easy.
Don't buy what you can't afford, and pay all of your bills on time. Pay the house off early, and enjoy the ride.
Spoken like one who has a handle on finances. I still don't buy what I can afford, just what I need. Not only will I enjoy the ride but if I have grandkids the cycle of poverty, drug abuse and uneducation that plagued my family will end.
