Some psychologists believe that, while practice is extremely important, there is a component of intellectual ability that helps determine whether someone will be good at something such as playing the piano. Psychologists David Hambrick and Elizabeth Meinz did a study in the journal Current Directions in Psychological Science on "working memory capacity." It is a core part of the overall intellectual ability and it can predict success in something like playing an instrument. They measured the sight-reading ability of pianists, which is the ability to successfully play a piece of music they have never seen before. They studied two pianists who had accumulated the same number of practice hours but had different levels of working memory capacity. The pianist with the higher working memory capacity performed better on the sight-reading task.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
