The solution of a Rubik's Cube is not a series of individual good guesses, each surmounting move has twelve to one odds against success. It is a series of perplexed movements or algorithms that form a coherent method of returning back to it's original (correct) state.
The surest hindrance of success is to have too high a standard of refinement in our own minds, or too high an opinion of the judgment of the public. He who is determined not to be satisfied with anything short of perfection will never do anything to please himself or others.
The victory of success is half won when one gains the habit of setting goals and achieving them. Even the most tedious chore will become endurable as you parade through each day convinced that every task, no matter how menial or boring, brings you closer to fulfilling your dreams.
