9 ways to become an expert

Who reads 1000 books on a singular topic? No one. But if you do, you'll know almost everything there is to know about a topic. 1000 not enough? Read 10,000.

As you read, take notes. Then write about what you've learned. Write publicly. Write on LinkedIn. Write on Twitter. Pretty soon, you'll be known as the person for that topic.

Offer to give free speeches to clubs, associations, business schools or conferences. Tell them you're an expert in X. Prepare like hell to give the best speech ever. Deliver it. Get it recorded. Then put it up on YouTube (see next point)

Whether it's on IG, YouTube, TikTok, find a place for your video. Upload videos every week or two weeks or month (the shorter / more frequent the better).

Don't let others brand you. Come up with a personal brand that you are working towards and tell everyone you know.

Find opportunities at colleges or universities to teach the subject. Now you can call yourself an instructor or professor.

Using what you have learned, write your own perspective on the topic. If you want to find new ideas, find really old ideas and rehash them with your spin.

Using your book, create an online companion course about the topic.

Podcasts are always trying to find people to interview / topics to share / content to fill the time. Offer to be a podcast interview for related topics (if you want to be an expert in crypto, find podcasts on money, finance or digital transformation).
