When you work on mastering a language it starts with learning the basics. First you need to learn how to write letters, both capital and lower-case. Then you need to learn how to combine letters to make words. And last you need to combine words to make sentences. After that there are all sorts of other things to master. Sentence structures, proper punctuation, and an endless array of weird language variants. But it all starts with the foundation formed through learning letters.
Building your life is very similar. You have to first build your foundation, your understanding of the world, and only then can you start worrying about things like sentence structure and passive voice. Life is ever changing, but building a solid foundation is the only place to start.
