A good paper contains many interesting ideas backed up with an adequate number of pertinent examples.
Successful writing depends on invention, the generation of relevant ideas.
Many people have trouble getting started, so begin the process of brainstorming early. Just write, no matter how nonsensical. Be prepared to throw away a lot of useless words. You will be surprised at how many really good ideas will remain. Very shortly into the writing experience identify a hypothesis, a tentative focus for your argument.
