Second notebook entry

Today was a boring day at work, because I had nothing to do. I have had to wait until my boss can give gave me a project to work with and meanwhile I have had to study for my certification.

I hope to be working on something tomorrow... If I don't, I think I will be sleeping on my desk all the working hours.

So that's all for today! Over and out.

That is fine, but I think this sounds a little more natural:
