Enthusiasm!

My boss came to me and asked my oppinion about a job. On top of what I'm already doing, to cover the maternity leave from a colleague.
I said yes: it's a category that I know, but a different channel.
I didn't think much of it, apart from 'well, I need some spark, I'm trully and well bored'. After saying yes, I went a bit... 'hey, am I going to deep on this? Am I gonna go over the head, into areas I don't know? And destroy my reputation?'
Then the weekend came and I forgot about this, nothing really.
Only when I returned, it was a 3 day weekend as I took monday off, my boss called me into her office 1st thing in the morning where I met her and the other future line manager. And... from then on, full energy just flew!

The key reason I think is that I really like the category. I've worked in it for years and years and I know quite a lot. So very, very quickly I picked up on the projects.
But the excitement...! Huge. Overwhelming. Couldn't stop working. Time totally flew by.

Why?
Because I'm good at it?
Because I am much better than the rest of the people?
Because I can quickly add value?
Because I like that category a lot.

Don't know.
But it'll be interesting to find out as the passion and willing to work was extremely intense!
