I've really heard many people saying that don't start your day by peeping into your phone for you may spoil your entire day because of any bad news that pops up in the early morning. But I don't go by this logic. Because sooner or later you have to face the truth. So it is better only to let things go and not let such things have a deep impact on your mind. It is only your self control that you can exercise in case you have to face the harsh realities of life. So obviously if the price drops and you know that, try to explain your mind and have a control over your mind. Instead of spoiling your entire day or whatever!!
