I once read a blog post with an exclamation mark at the end of every sentence. I would have liked to read the whole post, but I couldn’t—the exclamation marks were distracting me from the content and making it a painful read.
How to fix it:
Proofread your work. Then ask yourself: Does this sentence need an exclamation mark? Am I going to lose anything if I replace this exclamation mark with a full stop? If the response to this question is ‘no’, then please, please get rid of that exclamation mark.
