Buchanan,
Writing can start with what you think and may have much to do about what you or how you would want to play it. I suppose there are a lot of models we can all pick from. At this point in time its a writing on a paper, which can be molded into many forms by word changes and thoughts.
Should others make suggestions, it would be for bringing out other possibilities to glean from. They may be a plus or minus to what you have in mind.
It has been mentioned, not to go into this as being bored, rather a quest to do your best, including changes that may occur while you work on this lyric and the tune.
Don't go into this thinking its not very good. I see you have a layout on the chord progression so you must have something in mind.
Good luck with your progress.
