Home improvement is an obligation every homeowner should feel. However, not every home owner should attempt it himself. Sure, you can save a few bucks by not hiring a professional. But when you climb that ladder to the roof and end up on the ground, you'll find that all of a sudden you have all the time in the world to find a professional to do the job as you heal in your bed. Hiring friends to do the work is no better. You'll find you have no choice but to laugh as your friend bursts through the wall you're trying to demolish, and it's impossible to tell someone they're going to have to pay for all the damages while laughing.
