Time and Change aren't measured by the same ruler.
Few days ago I was cheering giving linux classes to my technical grade students. Now I got 3 linux classes under my rule.
It's a happy day for me. Time for celebration, for looking forward to my dreams and of course, to work even harder than before. And it is best that I cheer now, because going 20 hours of hard work each week will get my ass flat.
Happiness lies in the knowledge of a fruitful future doing what we like to do and do well.
