This is how I write, in five simple steps:

1. The problem: show readers that there’s a serious problem that needs to be fixed.
2. A possible solution: explore one or more possible solutions to the problem.
3. Solving the problem: tell the story of how to solve the problem using one of the possible solutions.
4. Drawback: show that the solution is not perfect, after all, and present its disadvantages.
5. Final decision: decide if readers should stay with the problem or opt for the proposed solution.
