There are no rules. Some things you can only truly learn by doing, and writing is one of those things.
Form opinions. Try different methods for getting things done. If something doesn’t work for you, try something else. Keep trying until something sticks. Keep writing!
Still, there is some value to advice. Sometimes it can speed up the learning process. A single sentence or concept can force understanding to click, suddenly and permanently, into place – but that won’t happen until you start writing. So keep writing!
Oh, and don’t forget to set aside time to read. Now, please get back to writing. You’ve wasted enough time surfing the internet my dear.
