Stated more traditionally, “there’s more than one way to skin a cat.”
The great thing about roadblocks is they force an evaluation of goals.
For example, you’d like to publish a book and are continually rejected by publishers. Is is that you want to have a physical book on Barnes & Noble’s shelves or that you want to share your ideas with the world?
One answer says mold yourself to what publishers want and wait for them to like you. The other says start a blog over lunch.
