I am really so tired.I can imagine that work will be like that next time too.just endless toiling all for nothing.everything is so meaningless.if I sacrifice my first class,will I be happier with more free time to spend with others?cos even when I go out with others now I feel so tired with nth much to talk about except my sad life.how sad indeed.for consolation,it's abt half a yr left b4 all this toil is over.although a fresh new level of toil will begin,but I really can't stand this life of isolation.maybe it's really really time to rethink abt my priorities.although it always has been time but better late than never.I tink I finally experience what Ecclesiastes is talking abt,not just understanding it.afterall,what's the best way to learn than to experience and learn it the hard way right.
