My issue isn't with coming up with story concepts in the first place. I have about a million and one ideas, and then some. My major problem is that I can't seem to come up with a solid conclusion or climax for any of them, just a conflict. Whenever I DO come up with a viable option for a climax, it seems like it lacks tension. Does anyone have tips or ideas as to writing exercises or something of that sort that can help me with my plotting problems?
