Here comes a new idea. It involves revisiting an old idea. It may require some humility - for you will have to accept something you previously rejected. And it will involve faith, for you cannot be sure that the idea will work until you try it. But all other ideas are not working and you really do need to progress. So, as you now have an idea about why an idea did not work last time, what harm can it do to try that old idea again in a new way? Any attempt to understand what once baffled you will turn out to be a good idea
