Narrowing down ideas (Reflection)

What I can reflect from narrowing down the ideas is that there are many good ideas for a performance but there are only some that can be used. Like for example in our class, in the beginning, there were 20 ideas and then, it became 12 ideas  and then, finally to 10 ideas. I think it was good that narrowed down the ideas or else we would we have so many ideas. :)
