Ever tried taking flying lessons from a Chicken?
When you take your expert knowledge from the wrong people, it never ends too well, especially where Money and People are at stake.
Just as importantly, don’t gamble with life. Everything worthwhile is built from the ground up, one single brick at a time. If you try to rush through the building process (or hire a bunch of people whose expertise are limited to Lego constructions and Sand Castles), the whole building could come tumbling down and even mess up your hair.
