rubbish??

have u ever go back and read what u have written in the past??
like a diary, or maybe some old letters, or maybe older posting in your blog??
sumtimes, i can laugh at my silliness in the past...
or sumtimes, i can also learn from my past experiences...
but sumtimes, i regret what i have wrote...
i might wrote sumfin which seems right at that time,
but a moment later... when i go back and read it, they're all make me seem stupid...
or contradict what im doing in the future...
which means i cant keep my own words...
and now i'm wondering....
are all those postings that i've written juz going to be rubbish in the future??
