Bad ideas do not work, no matter who supports them.
You can get your family behind you. Your friends can voice their approval. Even your Pastor can vocalize his support. If the idea is terrible, it will not work.
Good ideas work even with little to no support.
People can tell you that you are crazy. Critics and commenters can declare how this will never work. But if the idea is good, it will work.
This is true in business, politics, and even the Church.
Perhaps we should spend more time making better ideas and less time making pleas for support.
