Share your business idea
Nowadays, the world is full of ideas. Everywhere. Brilliant world-changing ideas might be scarce, but the probability that yours is one of them is small. Be sensible.
Even current technology leaders were not the first in proposing what they do, e.g. Apple, Google, Microsoft, Intel, and many others. So when people ask you about your idea, share it, the advantages of spreading the word are much higher than keeping it in secret.
What counts is an outstanding execution. Move faster than the world. Your idea will surely change during the way, your team and especially your clients will lead you to success.
You cannot sell if you do not explain clearly what you do.
