Unfortunately it is extremely important for survival. But if we focus on having it, or wanting to have it, it can ruin lives for the most part. Like my husband,. He feels he can never make enough money and I am all about stability and living a simple life. So it stresses me out. Also I supported him for 2 years and I finally told him that he either has to pay half of everything or he can go live with his sister. Even though he helps now (he could help more) he is still stingy with his money.
So the best advice about money...don't let it ruin you. Also life is too short to worry about trivial things.
