The dangers of purposeful isolation in today's age is that you bar yourself from possible admittance into any of the ciques that are so necessary to frequent for any of those who wish to get into any position that is even rmeotely powerful or influential. That can still be negated, however, by being born into certain bloodlines that are already powerful or influential by themselves, you inheriting their positions. But to thosee prone to isolation and/or unable to gain access to one of many cliques that also lack elevated blood, perspectives are somewhat bleak. Note, however, that belonging to one of these groups is a requirement to climbing life's steps only if you are to climb with others. And we all depend on others. Our upbringing is not done alone. But there comes a point where one must branch out, or be forcefully removed from the trunk. It can be a hard decision to make and separation -- not total, but partial -- can take a long while. Back to the main point: Those who do no fulfill any of the criteria needed to go up the steps with others, resort to making the climb alone, or not attempting the climb at all. But how much more difficult it is to climb alone, for those who do, for you're left with no one to rely on! We all carry our shortcomings with us  -- some can be worked on, some completely overcome by change from within -- but some do stay with us forever. And without anyone to have our backs even the slightest of falls can become fatal.
 Even worse, still, is to arrive at the top only then to realize that you carried with you a worm, a parasite, a vicious tumor on your character, one that so took over you that went by unnoticed to your own self. And with no one around you to extirpate it while still young, still forming, from an unable you on that same state, what was there for you to do?
