Oh! There are plenty of tips I could give! Remember to practice! Try not to procrastinate too much! Write in your native language unless you are certain you have a good grasp on the other! Don’t capitalize randomly, get a good spell check, and use grammar properly. Don’t make run on sentences, get a proofreader if you can, don’t forget the oxford comma, don’t treat writing like a chore, and be nice when you receive criticism because they’re just trying to help you get better! Hope that helps!
