You won't become a master essayist overnight. But, conquering a few of the most persistent problems that show up in your writing will be a huge help in terms of strengthening your writing overall. Building your confidence is key to becoming a practiced, better writer. Academy videos and a writing textbook - if you have one - can be great tools for this. Select just one writing concept at a time, take thirty minutes to review the rules for that concept and do a few short practice exercises to see if you can get the rules down. Remember: try to take on concepts one at a time to keep from feeling overwhelmed.
