I really like the first one : No one will ever be as excited about your [product, service, business] as you are. That should really be the first thing to say to a new entrepreneur : "noone cares so you better be prepared to fight".
"In reality, it’s been more like being a shepherd trying to herd a flock of ambivalent geese through an obstacle course."
Maybe that should be a cue to make your product or service more valuable and exciting, with fewer obstacles. If your customers don't love you yet, you need to do more for them.
