Time flies without your notice when you fully commit and focus yourself onto something. You also immerse and forget yourself in it but you gain the purest experiences: peaceful, sweet, excited, happy or sorrow.
I need to train myself to master the trigger into the mode since this mode not only gives me peace and joy but super high efficiency. Time flies, but this super high efficiency makes you achieve more as if your life is prolonged.
