If your job is to write or edit, chances are you have been given a style guide to help you make important decisions such as which words should be capitalized in a title or headline.
Or whether to hyphenate if you're writing in industry that could easily be overrun by hyphens, such as the financial services industry (or financial-services industry, wherein you'll find estate-planning attorney or estate planning attorney and wealth-management specialist or wealth management specialist).
Or how to punctuate and capitalize the information in bullets.
If you're ever unsure about, for instance, whether you should put a period after the information in a bullet point, here's a tip: Ask if there's a style guide for your work. All publications either follow a style guide or have one of their own (e.g., the New York Times Manual of Style is for the obvious, while most other journalists will follow the Associated Press' Stylebook). Depending on the field, you may have be governed by the Chicago Manual of Style, the APA (American Psychological Association, and it's not just for psychologists) style, or the MLA (Modern Language Association).
If you're writing for yourself, hoping to be published someday, write in the style of the field and genre that you'll soon be a part of. If you're writing for someone, let's say a small company, who doesn't have a stylebook, you should at least always be consistent when it comes to style. Make sure all of your bullets have the same format, punctuation and capitalization. If you use hyphens, make sure you use them in the same way throughout the document.
And if you want to try to make a couple extra bucks (I've done this, by the way), ask your client/employer if you can (for a fee, of course) create a style guide to prevent future streams of questions by allegedly nitpicking writers and editors.
