Nope, not the ones we use with an asterisk (e.g., "f*ck - this project will never end"). I recently read an article (https://www.entrepreneur.com/article/233318) that happens to be from 2015, but is still valid today. The word is "just", as in "I just need 10 mins of your time", etc.
I didn't stop to consider how this word "diminishes the importance or difficulty or an activity." You can guess how this word doesn't help in negotiations or pitches, either. I've been more vigilant in the past few weeks, and man, do I use "just" a lot. NO more.
See how much you use it today, and let us know if there's a difference in your writing.
