Confused State - What to do

Question

For last couple of weeks, I am in a confused state. What is new topic to start? I am trying to start books (free for C# Corner) on 3 or 4 different topics.

First, I started writing a book on Mono for Android and suddenly, the Mono team was fired. Hence, there will be no Mono for Android. So, I can't continue this.

I am working on SharePoint 2010 Development book.

I just started looking at Expression Studio 2010. But I need a 32 bit machine for that.

Next topic I wanted to finish is Silverlight 5.

I started iPhone development as well.

So I can't focus. I think I need to take a break and forget about it for a week and come back again :)

What do you suggest I should start first?
