At the beginning, we start out with our bits and pieces. Make sure you don't only plan for the outer shell, if the core function isn't there, it isn't going to be useful, so plan this early as well.
We need to break down what we want to do, and divide the work up into sizable units.
Then we have to shape each into its required form.
Polish your work with some decorations, this gives it the flare that makes it stand out.
Make sure each one is stellar on its own.
When the parts are all whole, complete the sum.
Things take time. Keep going until they are done.
