Why sharing your know-how is the most enormous advantage?
Now we live in the Information Age. It means we share more content from more sources with more people more often and more quickly.
We taught ourselves from others who shared their knowledge (either on the web or in books or otherwise) for us to educate ourselves. If that weren't available, we wouldn't know anything about it.
Don't be afraid of sharing your knowledge with others!
Some people are scared that someone will use their knowledge to become more intelligent suggests they don't understand how education and conversation are created. No one wants to hear "all you know" on a subject unless they specifically ask, but appearing to know nothing at all on a topic that others are discussing, sets us aside as not participating.
A good example is sharing a cake recipe with a friend. A person is willing to share the recipe, to begin with. But a friend will never make it exactly like theirs because each of us has a "secret" ingredient which can make a cake much better, even it was based on the knowledge of others.
Because from that knowledge, a friend can create their own version of the recipe, but it's still will be a cake in the end, wouldn't it?
People who hear what you have to say can take away as much of the information they can use or care about and, if they choose to learn more, that's up to them.
Knowledge is something, the more you share, the more it will grow:
— You stay motivated: you can share the knowledge others appreciating you and pushes you to become better at what you do.
— Getting top talent access: knowledge sharing helps you get feedback and help from talented people.
— Recognition: by sharing your knowledge with others, you have an opportunity to identify you as a valuable expert.
— Generating new ideas: two heads or more thinking is better than one. So you can share the knowledge when new ideas are getting.
Knowledge shared is power squared. It helps you to improve the knowledge of the person who takes it from you and also helps you critically evaluate the one you have.
This is really true.
In general, I think teaching is the best way to learn, to feel motivated, and useful. It doesn't matter if it's direct teaching, via a blog, or an answer to a post.
Since I have my blog and I teach web development to beginners, I never learned that much in my life, and I never felt that good by helping others!
Huge +1 on this. It also can be a great source of quality leads and prospects for whatever you're building. Much of Close's marketing was (and still is) basically this: sharing knowledge that's of value for sales teams.
