A lot of things can only be seen when are observed it periodically. The smallest things which people normally neglect are the causes of big problems in the end. Only by boardening out your mind and see every single details (small things), you can then solve the problem. BUT out of 10 or even 100 small things, only 1 of them is the true cause, the others are all nothing but noises to confuse you.
