Sufferring mental/writers block

So Ive got myself signed to do my second toastmasters speech next Monday and I cant think of what to write and/or where to begin.

I do know that I want to speak about personal development and its different aspects. I want to present from a purely practical point of view.

I was thinking the title of the speech could be "Personal Development: Whats it good for?"

I think I'll visit StevePavlina.com and BriamKim.net and collect 10 or so articles and make a speech from that.
