When I buy something I ask myself that 'is this really important to me?'. And I can afford to buy it then I finally determine to buy it. And I browse again because another sites often sell same product cheaper price. But I often determine something impulsively without thoughts. Sometimes I'm gonna trying to decide for a long time if I should do something because it is very important to me. And I feel very tired to think about that and I suddenly conclude that problem and avoid thinking about that again.
