Programming and Writing have in common

Have you ever heard someone say? "You build it before, build it again".

Its like telling a writer to rewrite a book word for word. You will be able to write the story again but not word for word. Its impossible! Creating applications is the same when coding you're in the present and the creativity is flowing but once you leave that state you may have to start all over (research) to recreate the application. It's important to document all your discoveries.

Don't try to learn every function in the language but be an expert at the basics and add as time goes.
