What is the most important part of writing?
The purpose of writing is to communicate one's thoughts. Therefore, the most important part of writing is to clearly communicate one's thoughts. Verbose, overly extravagant, confusing writing does not represent "good writing"; it represents verbose, extravagant poor writing. It is poor writing because it is confusing and does not clearly communicate the author's thoughts. From this perspective, you can take the pressure off of writing as some large, unconquerable feat. You don't need to be the most eloquent, charming wordsmith to be a good writer. You simply need to clearly communicate what it is you are thinking.
What are study skills?
Study skills are what's called "metahabits", that is, habits that transcend a specific subject or task, and instead apply to a particular field of activity. For the metahabit of study skills, we are referring to the habits that you can form (or not form) to refine your ability to study, in general, regardless of what subject you are focusing on. For example, eliminating distractions, identifying clear goals, and placing time constraints on oneself are all time-tested habits that improve one's ability to effectively study. Once obtained, these skills can be applied to improve one's ability to study any subject or discipline of interest.
What is the value proposition being offered by the company and how is it being communicated to the public?
The value proposition offered by the company is the product or service it provides to the public. If the product or service they are offering to the public is of value to the public, the company is in a position to do business. It is the marketing department's responsibility to communicate this value to the public in clear and effective terms. A company's value proposition is typically communicated to the public through digital marketing channels (e.g. website, email, social media), media-centric marketing campaigns, branding, and other similar marketing tactics.
