Mm.. I should not try to have unhappy posts.
Think about it this way...

By turning to this blog only as a way of venting my frustrations, I will end up documenting all my sad or angry moments, while the happy moments turn to dust.
I don't want to look back and see a backlog of sad posts.

Perhaps I could write down my frustrations in temporary documents, and jot down my happy moments on a more permanent platform. Then one day... when I'm old, I can read my memories.. with the sad ones faded to an illegible blur and the happy ones etched forever :)

Stay optimistic! Think happy thoughts!
