All publishers are Columbuses. The successful author is their America. The reflection that they-like Columbus-didn't discover what they expected to discover, and didn't discover what they started out to discover, doesn't trouble them. All they remember is that they discovered America; they forget that they started out to discover some patch or corner of India.
Mark TwainAll you need in this life is ignorance and confidence; then success is sure. You can "already know for sure" things that could actually impede progress. Always be on the lookout for the things you did not know, that you did not know. Secondly, work on strengthening personal belief that a particular will be achieved regardless of any adversity that may show up, or evidence to the contrary.
