There is an antenna in the mind whose functioning must be studied, and from which the best decisions often derive. It is difficult to understand it because, sometimes, circumstances are not enough to justify its action. The common case is one in which these remain the same for a prolonged period of time, often for years, and the antenna remains silent, without picking up or emitting any signal. Then, suddenly, it awakens, picking up infinite connections at once, recommending immediate, urgent action, even before it is clear what needs to be done. This is followed by a flurry of ideas, and the attempt to organize them is overshadowed by the feeling that a lot of time has been lost. The agitation becomes painful; if it is nighttime, sleep is impossible. Finally, after a few electrifying hours, thoughts become organized and allow for deliberation. What satisfaction comes after!
