actually we shouldn't be unhappy... cos being unhappy won't help to improve things...

but u can't help but being uphappy when things are not gg ur way rite?

well, i watched this drama then one of the character said that according to this philiosopher, human feel unhappy becos they can analyse and see what they are having and not having, and feel sad over wad they do not have; while animals do not think with such complicity, they simply see things that they have and is contented...

having is also a kind of not having... they are relative... so when u do not hav sth, think relative, and u may realised that actually u have got sth:D
