Working on Saturday!

This is the first time i in my short working life that i am working on a saturday. ( i mean i may not even work on a weekday)
It is more by choice then by design do no regrets or anything. But its good to have some feeling of being able to take stress and deliver on the job. ( i know this " deliver on the job" is completely perception of others especially your boss) but i am more concerned by self satisfaction..and to top it ...i am feeling like i have started learning something abt business...thank god..Finally i am learning!
