How stupid can you be?

Quite stupid.

I used 9 hours yesterday to create two tables. Today I found a mistake. Since I wasnt been capable to re-arrange the original data-file in R with a neat line of text but instead picked and glued numbers in excel for hours I have to do the same from beginning. GRRR. It is boring, frustrating, useless re-working after one little un-concentrated moment. And worst of all I almost know how to do it a lot easier in 5 minutes. But not quite.

And it doesnt help that the people working at our department have kids in several kindergartens and get all sorts of flues from them. Read: somebody has infected me with some sort of flue which makes me tired, un-motivated and un-concentrated.
