Leaders are forged, not chosen. So stop asking for permission to be special.
Martin Luther asked nobody for permission before nailing his 95 theses to the church doors. George Washington didn't ask for permission to carry on the American Revolution. Bill Gates didn't ask for permission to revolutionize the way personal computing would work.
These leaders had faith in what they believed in. That faith is critical to anyone who wants to make a change. Without faith, there is no "leap" and without the leap, there is no change.
Have faith that you can do it and that even if you fail it won't be the end of you.
Lasting change won't be made by asking for permission. You need to do and figure out the rest of the stuff later. While those who have faith are willing to be martyred, they're also fit to be glorified.
