What is happiness When we hear the word “happiness”, we probably think of our exciting emotions, wonderful news and brilliant relationships. Although we have learnt “happiness” while we were kids, it is surprisingly hard to define the meaning of this word. In the first place, happiness is what we look back. Even though the things have gone, the memory is still in our mind. Be it negative or positive, as the time go pass, our brain systems will eliminate the majority of unhappy feelings and eventually exist lots of happiness. I also want to use the timeline (now and future) to showcase the the reason why happiness is always in our mind, but I have been studying the most difficult subjects and is out of time now, hope all of you can give my writing some sugggestions below!
