In general, purchasing something on impulse sounds negative meaning. It may mean purchasing something unnecessary without deep consideration. However, I envy a person who can buy something on impulse because I tend to spend a lot of time before buying something. When I have an items I am planning to buy, I look up the reputation about the item on the Internet, and compare it with others which another company produce. In addition, I wonder whether it is the best time to purchase it, and where I should buy it, and so on. Sometimes I give up buying it because I fell tired from examining it.
Therefore, I sometimes wish I could buy it on impulse, but I can’t because it is caused from my personality.
Honestly speaking, I understand there is no big difference whether I spend a lot of time to examine what and how to buy.
