Do the ideas you have matter?
What makes you think you have good ideas?
Where's the proof? Where's the evidence?
Why do you continue to share even if there's not much support for what you believe in?
These are all questions that come to mind when you have a new idea or when you're promoting an idea you believe in.
Some will support your think and others will look the other way.
For me, what keeps a new idea alive, is the knowledge that the idea has potential to make a positive difference in someone's life. How about you?
