We have to go through hardships & unhappiness to see what happiness really is. At the same time, sometimes, we also need to face or make undesirable choices; the choices, which we know, beforehand, will make us unhappy at that moment, but it is better to face that unhappy or undesirable moment than to keep suffering, while keep a "happy" facade on our faces.
Sometimes, in life, it's indeed better to not know the whole story, because then, you lose all hope, & become hopeless & bitter in your attitude. You might even become pessimist. Even if we are suffering from a bad situation, we still hope for the best & pray for the good times to come. Sometimes, not knowing the whole story, helps us enjoy & appreciate the present moment. Perhaps, that's why, God kept some important information away from us, like, our time of death.
