Writing and Public Speaking
The greener you are as a writer, the more generous you usually act with exclamation points. Taught during early grammar school as an important punctuation and typically allowed to fester by grammar software, it really needs to be used less in writing - even less than the few times it is usually employed now.
I've seen someone write that you get a total of three exclamation points to use in your writing career and no more. While that exaggerates the idea, it makes the point perfectly clear - exclamations can be done without in most forms of writing without the littlest negative repercussion.
When a sentence ends in an exclamation point, it usually sounds either tacky or out-of-place. If you need to add an exclamation to stress an idea, it's a good sign that your writing needs some work. If you've ever written anything with this kind of punctuation, try reading through it again - you'll find that you can usually strike it out and rewrite without much problems.
Of course, there are pieces where exclamations come naturally. In fact, that's the only time you should ever use one. When a sentence, thought or expression naturally requires it, the necessity is obvious - otherwise, don't use them.
For business writing, in particular, exclamation points are a huge no-no. It accomplishes nothing yet can paint you as an unnecessarily rude individual, especially when you generously add them to your emails and other forms of correspondence. Imagine me, for instance, ending this piece with an exclamation point. What does it do to help? Answer me!
