During these years, I have developed a number of applications for my offices, myself, my church. I found this is very fast and easy to jump into writing code. The application will be developed in very rapid style.

But after a few months , maybe in a year, I have no ideas to upgrade the existing application. Even myself, I can't follow my old logic to conitnue build the application.

I need to do a good design first and then write a set of libraries or framework. And then I tested the framework in deep. I can have somethings solid. ( I need to do that, even I write the application for myself ). Moreover, I will well documented too.

I need to do the things structurally!!!!
