How to use this example for your LinkedIn summary:

While you’re probably not a high-profile celebrity like Ryan Reynolds, his summary is a showcase of why showing your personality works.
He starts by making fun of LinkedIn's “business language,” which we all know is true. Then goes into how he’s on a sabbatical from acting to work a 9-to-5. How funny and odd.
He pokes fun at the praise he’s received from the Wall Street Journal and his own skills.
While he doesn’t have a call-to-action (because he doesn’t need one), he comes off as an authentic human whose on-screen sense of humor matches reality.
How to use this example for your LinkedIn summary:

Be human and show you’re personality. Ryan’s funny summary is a perfect example of how you can become more approachable and likable on LinkedIn.
Add in a spice of humor. Hiring managers and potential employers won’t mind if you make a joke on LinkedIn.
Consider throwing in a joke when speaking about an impressive achievement or experience. Ryan puts on a showcase of how to do this with his Wall Street Journal comment, and anyone can add some similar humor to make their experience more interesting and relatable.

Why this works:

Marsha has a great hook. Everybody knows about the “for Dummies” books and probably has bought one themselves. I have several on playing ukulele and fishing, so by seeing that she’s a “dummies” author, I’m hooked (just like the fish I learned to catch from the books).
Awesome use of numbers with dates attached to make it even more impressive. She had already sold 1M books by 2007 and has had 20k podcast downloads a month since 2008.
Many people who hire consultants want to see things like what brands you’ve worked with and what publications you’ve been featured on. Marsha is super thorough here and builds a lot of credibility with her experience.
She gets into the specifics of what she offers to her clients (selected brands) and addresses a common problem they all have around community building and online customer service. This gives brands a clear reason to hire her or at least reach out.

Dig deep into the numbers and dates. For example, if you sold $10M worth of software, during what period did you do that over? $10M sold between 2019-2022 sounds more impressive than just $10M sold.
Dig deep into the impressive companies, brands, and publications you’ve been a part of. You could consider listing brands you’ve sold to or collaborated with and publications your work has been featured in, rather than just companies you’ve worked for.
Be specific about what you are offering clients and/or employers, and talk about the problems you will solve for them. This is more compelling than just listing experience and results on their own.
