If you have an idea and you want to impact people with it, you will need to make it tangible in some way. If it is an online course that you want to produce, you will need pages for students to use, and you need to have an email responder in place to funnel people in the right direction. If your idea is to open a restaurant, you will need to have a location, employees, vendors, systems, licenses, and don’t forget hours of operation. If your idea is build a non-profit organization, you will need to have a way for people to donate money and a mission to inform people of what you are wanting to do with their money.
If you want to keep your ideas to yourself, then that’s fine. Eventually, you’ll just move onto another idea. But if you never make it tangible, it will never become more than an idea. The magic happens when action is put behind an idea. Spreading ideas builds momentum and pushes people to dream ideas of their own.
