It's important to validate your idea before you even think of building it. You want to make sure that it's not a waste of time, with no market, that's why you want to share it at first.
Personally, I've feared sharing my greatest ideas, out of the fear that someone someone would take my idea before I make it. But if I at least began making it, I reasoned that it would deter people from stealing my idea, since they see that my idea "has already been done", so they wouldn't bother.
I was wondering, does/has anyone else gone through this?
What are your recommendations when it comes to the best mindset to have when it comes to Sharing your project?
