A lost cause could be otherwise defined as someone or something, a project, a purpose, or a plan which no longer has hope of winning. It is a defeated plan, a disappointment-laden purpose with a perpetual dead-end. The cause is fruitless, it is lost.
I am MJ.
Some brilliant “causes” are prematurely abandoned or take a long time to discover. When I discover a cause I will show it to you. No longer lost, it will be found; honored and promoted.
Welcome . . . to the world of MJ’s Lost Cause.
