I initially placed the title as "memories" but have decided to change them to "feelings". I find it easier to recall happy memories than sad ones. Perhaps I am not in a happy state most of the times so it's easier to recall something happier.

But I find it weird that we spend more time complaining about an unhappy feeling than making a bliss feeling last (not like it can last much long too). Theoretically speaking, I am guessing the ratio of positive feelings to negative feelings should be quite evened out in our life but it seems that we experienced way too much bitter feelings most of the times.
