All 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.
Mark TwainThe master minds of all nations, in all ages, have sprung in affluent multitude from the mass of the nations, and from the mass of the nation only-not from its privileged classes.
