If you are unsure of a course of action, do not attempt it. Your doubts and hesitations will infect your execution. Timidity is dangerous: Better to enter with boldness. Any mistakes you commit through audacity are easily corrected with more audacity. Everyone admires the bold; no one honors the timid.
Robert GreeneI have an argument that to master any field, it's simple: it's a function of time. How much you devote yourself to the process, how much experience you get, how much you're willing to expand your limits, how willing you are to develop your own style. If you're willing to put 10,000 hours, something amazing is going to happen.
