If you find you have too much to write about, narrow your topic down if you can be that specific. For example, several ideas can be picked out of FLLV - failure, travel, tradition of the trickster. Staying on focus is the main task. A good essay flows naturally, building each argument stronger and stronger. By the end, you should have convinced your reader of something.
Tone is fairly important.
But not really appropriate unless your English teacher is an ex-hippy or something. Using your skeleton, write one or two paragraphs for each point. This is a good skeleton because you can pick out specific events from the book and write specifically about them. This is why the outline is the skeleton of your essay - it's strength will be your strength. An essay is easy to write when the ideas are specific and clear, not weak and vague.
