Speeches / Advice on the format of a speech [2]

Hi Guys

I recently starting writing and delivering speeches but got stuck at a certain point. So if anyone can shed some light that would be great.

My first couple of speeches I would write the speech down and then memorize it completely. After some research I found out that you should not memorize your speeches. What you should do is to write a speech down then break it up into different ideas. You then associate these ideas with words and then write down every word on a card. After this every time you deliver the speech you see the word and speak pretty much of the cuff.

My problem is that it seems when I'm writing my speeches I have to many ideas to do this.

Here is a couple of piece to give you an idea what I'm talking about:

As we arrive the colored collage of tents and people fill up the area like a Giant's Smartiebox being poured out onto an empty field. We queue up for registration and check in but the long queues are almost comparable the ones found at the vehicle licensing department.

In the above example there are 2 ideas. Does this mean I have too many ideas in a short space?
Any other advice will also be appreciated.

Thanks
