More on the application of one's energies

If one devotes his life to a cause, must he choose between: a) living body and soul in a way that allows him to move toward his goal with every action he undertakes (if this is even possible), or b) divide his energies and live his life with an awareness of his tendency to repeatedly distract himself from his goal, and thus live with the guilt that he inflicts upon himself as a result of the faltering nature of his attention and work-ethic, or c) recognizing that even those actions that are seemingly ineffective - with regard to the attainment of his goal - may actually cause him to work more effectively when he is working directly toward his goal, because such "distractions" improve his mind, by supplying it with a diversity of stimulus on which to fixate, and refresh his attention-span by way of providing his mind with breaks that may keep the information and thoughts required in the process of working towards his specific end from becoming dull and from being abandoned altogether.

If the latter is the case (that is, if distraction is actually beneficial), then should distraction be sought out in extremes, or in ways that are purely mental, or in small quantities? Would huge distractions lead to huge amounts of mental rejuvenation, or must a balance be sought? Should distraction only be sought in the mind, and should every kinetic or tactual activity pertain only to the desired end? Or do activities and undertakings that extend beyond the mind, and subsequently to the body and one's actions, provide the mind with more inadvertent inspiration than thoughts alone? Can any of this be known, or must it be guessed at? And is trial-and-error even an option here, or will it create a pattern that may or may not allow for the greatest amount of productivity and may or may not be able to be altered or broken? As with most things, it seems that balance is probably best, although I must admit that I constantly wonder whether I should eliminate friendships that do not directly inspire me or aid in my work, even if the notion of doing so seems brutal and unkind.

Furthermore, if one's goals may (potentially) do any good for large numbers of people, or have any kind of positive effect on the world that might be more beneficial than friendship itself in some way, then doesn't one owe it to the world to pursue these goals instead of fleeting friendships, just because of the chance that they may be able to, in achieving or pursuing their goals, maximize their potential for positive influence on the world? Is the risk worth it? What if one fails in one's goals and also isolates his or her self? Then he or she has had no influence on others in a positive way at all.

Perhaps some people don't have much of a choice, and can only be pleasant company beyond a certain casual degree if they are simultaneously pursuing larger goals with potentially larger influence on mankind, because their disposition is such that they are unhappy or grumpy when not pursuing such things.

On an (almost) unrelated note, does prejudice stifle or feed the human will to produce or create? In a Darwinian sense, it seems that those who are persecuted are likely to want to reproduce in abundance (sometimes regardless of whether they can realistically support their children). Does the same happen with regard to ideas or creative/mental/philosophical endeavors, or does biology overshadow such "luxuries" as art and thought? Also, if injustice does encourage mental and creative progress, which in turn encourages cultural and political progress, then perhaps it is a positive thing in some way. I'm not saying that huge injustices or prejudices should be condoned or even tolerated, but this is still interesting to consider.
