What conclusion should you make if you do a project on William Wordsworth?

It depends on what kind of project. You might want to focus on a particular poem or similar group of poems that he wrote. You might want to demonstrate how his philosophy and beliefs (about religion, about love, etc) can be found in his poetry. You might want to compare him to other Romantic poets of his era. First decide what your project hopes to prove or demonstrate, and then you will be able to find a conclusion for it.
