First, let me commend you for taking the time to sketch out your ideas first. Too often, students just begin to write, thereby dooming themselves to an incoherent and disorganized product even before they begin.
Let's turn your sketch into a full-fledged outline. I'll fill in some pieces from your sketch. You can fill in the rest from your own ideas or from suggestions offered by other forum members.
A. Example of hope in action
B. Definition of hope
C. Thesis -- Hope is beneficial but can be dangerous
II. One way that hope is beneficial
III. One way that hope is beneficial or dangerous
IV. One way that hope is dangerous
A. Restatement of thesis
B. Closing thought or image
The overall tenor of your essay will hinge on paragraph III -- will you choose to offer an additional way that hope is beneficial or an additional way that hope is dangerous? That depends on whether you feel that hope is more beneficial or more dangerous. Choose a closing thought or image consistent with that assessment.
