Three Tools to Improve Your Craft
Write a journal -
It's been said before by many people that keeping a journal helps improve your writing. The act of throwing the words out on the page gets you into the writing habit (a very good habit to have!)
I've never been a journal writer, but I can't argue with the logic. There have been countless journalists over the centuries who have poured their emotions into a diary and became successful authors.
If you're finding yourself stuck, maybe you should sit down and write whatever comes to mind. You can't find the diamonds without digging through the mine.
