When building a house there are many aspects that demands extreme attention. In fact if not done carefully, your home could suffer from lengthy damaging problems, (I know, I worked in our family's construction business for years). The most important though is the foundation. Other portions could allow defects but if the foundation is not properly constructed, the house will eventually crumble. When you've built a solid foundation, the rest is not as painstaking, you can now structure the house following the plan and build a beautiful home.
But what is a foundation if you're left without a roof over your head? The home then becomes useless, rain would inevitably destroy all your belongings. Your would die come winter; and the summer's heat would make you feel like it's hell on earth! These facts stand true not only in the construction arena, but in almost every other field; if your start is not solid, your end will come down crashing. And if you don't take could care of what protects your foundation, you will lose almost everything.
