Guess What? Not every page of your book has to be a masterpiece. It is okay to have people look down on your capabilities because you have not accomplished anything in life.
You just have to learn not to despise small beginnings, the journey has to begin somewhere. You may be anointed in the wilderness but it can take years for you to see the manifestation of the vision.
Just keep quiet, endure and enjoy the journey of learning. Remember, the stone the builders rejected became the cornerstone.
