Answer:
Taking Notes and Planning.
Explanation:
This is a difficult question to answer because it varies per person but I would assume that it's the taking notes and planning process since this is where you would have to re-read the passages or articles and find which topics would be the best to talk about. Once this process is complete, the writing and revision would come naturally since you have already planned what you are going to write about.
This expression means that you don’t have to make a decision right about a future problem. You should decide what to do about that problem when the problem is directly in front of you.
