And I have to remind most of you; don't be doubters.
In life, one always hears: "It will be difficult", "It can't be done", "I don't think it would work", and then someone does it, and it is amazing.
Look for what will work, what could work and offer those ideas.
I'm sure someone once said "Riparian plants won't grow in an aquarium!".
As Ben Hawkins said in the show Carnivāle: "Everything's impossible, 'til it ain't".
