Our minds are very delicate and need to be treated as such. This is the reason why we must be very meticulous of what goes on up there as thoughts. What can take our minds can take our lives.

Hence if allow negative thoughts to cloud our minds, it's certain that our lives will also emit negativism in various aspects; and vice versa. The relationship between the outcome of our lives and our thoughts can be further explained by the popular expression used in computing, "Garbage in, garbage out."
