She told how people can change the world. A lot of people have some ideas inside of them, but she said that idea was powerless. If you like to change the world you must to pull your idea out to the others. But it should be effective. Also, if you like to change the world your idea must to have presentation form. In your presentation should be two stages. First called "what is", it is past. Second is future and called "what it could be". At the end of the presentation is new bliss, it is people's achievements. For example, Steve Jobs change the world with his mobile phones. In the conclusion she said that future was the world that everyone created. I like this video and the idea of this presentation. I think it is very useful, educative and interesting. Her speech teach us how to gain our points and how create future. This can force people to decisive solution.
OK, I've corrected your text (http://www.italki.com/entry/640380), and explained why it's essentially problematic. I suggest making a clearer attempt at your story, and avoiding the grammar that's so confusing. For example, you could quote the speaker directly then explain your interpretation.
The short answer is yes, you shift tenses because you're reporting a fact as true at that time. It's very rare that you'll have a situation where you don't shift the tenses.
There are also a number of other errors in your text. Would you consider posting the text in the Notebook section?
Thanks a lot, Peachey.
I've considered it already)) And posted it...but no one has not corrected it :(
