Weird and Hired

I just got hired by HSBC bank awhile ago. It is a very well established bank around the world and to be working with them is such an opportunity I think, but I don't know why I'm not excited working with them. I know that what I am supposed to be doing right now is to literally do a tumbling. But I don't know why I'm numb these days. Nothing seem to make me excited. Weird weird weird me these past few days. Better get back to reality A-SAP.
