Best way to project, plan and structure an app with CI

Before everything I create a new Word file to note down & follow the "to do list" of the project. When I complete a task, I strikethrough it, I also write down any link of any forum help or a link of a video etc. Then the work takes control of me and the work itself in a proper way.

And I continue by doing it one by one, seeing the result of each section, of course by copying some parts from the previous jobs. This might lead to getting stucked to a point until you solve it. (Because I spend a lot of time searching for a solution. I rarely ask for help)
