Gr8 Ideas always start with a borrowed pen and a rough paper

"Gr8 Ideas always start with a borrowed pen and a rough paper" is an interesting reality, Its very closely related to one thing that happened with my project.
I was given the deadline for submitting the concept of the project by my guide, and a day before i was to submit..I was still making some "Flying Castles".
Then came the Eureka moment, an idea struck me and I was looking for some paper to jot down the idea.There I was with no paper and pen as usual....I went near the bin and found one, I picked up that crushed paper and borrowed a pen from Mama(Security Guard).
That is when I wrote an Algorithm for my project and to me and my friends surprise, our project got selected in International Conference and now going to Seoul.
So I would say I needed 3 things to make my project success.
One- A Rough Paper.
Second -A Borrowed Pen.
Third- Of course an Idea.
