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 talent of success is nothing more than doing what you can do well, and doing well whatever you do without thought of fame. If it comes at all it will come because it is deserved, not because it is sought after.
