"If you have an Apple and I have an Apple and if we exchange these apples then you and I will have one Apple.
But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas."
If you have an idea — this is certainly cool. Even better, when you have a good or even brilliant idea. But the truth is that you don't always have the time or opportunity to realize this idea, while other people have time and opportunity, but they often do not know how or what to do.
Also just by sharing your idea, you can learn about the same good idea of another person. Don't ask how it works — we don't know. But it does exactly that.
"You'll never solve the problem if you think the same way as those who created it."
First of all, in order to solve the problem we need to admit that you have it. And the problems are many, of varying degrees of complexity and in different areas of life.
Also, if you don't tell others about your problems, then you don't love to look at their problems. And often, someone from outside is able to offer a good idea that could solve your problem.
"We have a daunting task — to find ways to extract this energy. Then, pulling her from this inexhaustible source, humanity will move forward with giant strides."
To create something you need to spend energy, it is often called creative. And one of the ways to restore your level of creative energy is to enjoy the fruit of creativity of another person. Thus a circulation of creative energy in the world.
Similarly operates the concept of creative energy here — creating ideas, you can acquire the energy of other people, which in turn, can spend on studying the ideas of others.
