Lofty goals can only be attained with a clear, singular focus. By training your attention towards the target, you'll be attuned to serendipitous opportunities that align with your goals, and learn to tune out the noise.
Agassi, A. (2009). Open: An Autobiography.
Que lindo es soñar despierto. How lovely it is to dream while you are awake. Anybody can dream asleep, but you need to dream all the time, and say your dreams out loud, and believe in them.
