Type 7(Head Triad)
Sevens are gluttonous fun-loving types who believe in experiencing what they want in life without restrictions or obligations. They want a lot and are gnawed by their wants enough to see them as needs so they "need" that juicy steak and "need" that vacation. They take care of their stuff themselves and aren't a burden on anyone so why shouldn't they be entitled to a good life? These natural optimists have a hard time accepting the stark reality that the world isn't as accomodating as they would like. Being head types they understand that but sevens are sevens so understanding something and coming to grips with something are two different things.
Sevens have a blind faith in the future working out for them. Their jumping-the-gun streams of consciousness cause them to distort the future as being just around the corner. If they keep their options open a little longer they are sure to get what they want. They also frequently believe they can have their cake and eat it too. They enthusiastically plan out rosy scenarios in their mind. The future hasn't yet made the details apparent that might show their optimism is misplaced, nor does it make demands on them or slow them down like people in the present do. They feel if they keep moving and anticipating they can stay one step ahead of being bogged down by all that. It goes without saying they don't sweat the small stuff and are always on the lookout for shortcuts that would get them to their happier more fulfilling future faster.
Sevens have addictive personalities. They tend to be adventurous, impulsive, exciting, and enthusiastic. The more common sensing-perceiving sevens tend to be focused on more physical gluttony and are the typical party animals. The less common intuitive seven is no less addictive but has as much a need for mental stimulation as a need for physical stimulation. All sevens need the potential for a more fulfulling life more than anything. They need something better in their future to look forward to. The one thing a seven wouldn't relate to in a million years is contentment and a lack of wants.
With their monkey minds sevens tend to be mentally agile and versatile enough to quickly pick up the basics of many things. They frequently have a wide range of intellectual interests and can converse about anything. They tend to find it difficult to focus however and are easily destracted by the temptations in life. More importantly they often overestimate their abilities and confuse what they know with true mastery. More than any other type they tease others with their unrealized potential.
Between experiencing the fullness of life in the present and restlessly thinking up rosy future scenarios their mind is in high gear and their attention is diverted. On a more subconscious level coming to grips with sobering realities in the present and unflattering things about themselves is put on the back burner. Wants are reframed as needs and real inner needs are neglected. Emotional pain is seen as unpleasantness and avoided. These potentially painful feelings are compartmentalized and take awhile to hit home but when they hit they hit hard. On a more conscious level the seven primarily fears being trapped or stuck in a rut. Being bored or deprived from experiencing life triggers "rut" fears. Sevens find it much easier to acknowledge that they fear a "rut" than they fear "pain". The fear of being stuck or trapped in a rut conveniently relegates the fear of emotional pain to a more subconscious level in the fear queue.
Sevens are image center last which makes them shameless, insensitive, and cocky. Like eights they don't see how they come across to others well. Sevens move the enviornment towards them to accelerate their mental gears to distract themselves. Fives in contrast remove themselves from their enviornment to deal with things from a position of strength. Sevens are unprententous and young at heart. Don't let their youthful energy fool you though. Sevens have one of the stronger egos. Should they face obstacles these resilient types have confidence that they'll land on their feet...and they do.
Sevens are naturally egalitarian. They don't like playing power games and would rather just be concerned with themselves. They are grateful for their "lucky" lot in life which makes them fun to be around. They tend to give people the benefit of the doubt. While sevens generally aren't nitpicky of others' minor flaws they often underweight or even overlook major ones.
In enneagram theory 7s are thinking-instinctive-feeling in that order. Their default emotion is fear and their principal defense mechanism is distraction. They accelerate their thinking center mental gears to escape the need to come to grips with inner issues in their feeling center. They conjure up potential rosy scenarios, crazy schemes, exciting ideas, and creative ways of looking at things. They use all that to keep mental activity high enough to keep their mind off coming to grips with unflattering inner issues, unpleasant feelings, and sobering realities. It's much like running around to keep their kite in the air. Once it's time for follow-thru, examining the details brings them closer to reality which is a drag: the sticktoitiveness needed for that job training, that having a website business means having to cold-call to get customers, having to get up at 5 am for that job you thought you wanted, that cute girl sure is clingy. Once details are involved the grass isn't as green on the other side so the seven finds new grass starting from the mental realm and repeats the process.
On a smaller scale sevens may engage in wordplay or other shameless nonsensical "crazy funny" behaviour to distract themselves simply because they got the "itch" to discharge their excess head energy into their enviornment. Many sx-firsts think they have more seven in them than they do because sx is a probing deeply energy to squeeze the most out of an experience while sevenness is about staying in motion to keep their kite in the air to avoid coming to grips with inner issues and feelings.
Unhealthy sevens are completely hedonistic and have no focus in life. They are childish and irresponsible. They have an insatiable desire for one thrill after another. They are complete slaves to their passions. More importantly they are proud of it all. They are proud of being totally free. When they start to get healthy they come to feel a deep regret over the unfinished chapters in their lives they can never do over again. These are the same unfinished chapers caused by them mindlessly skipping from one thing to another. When sevens realize true happiness comes from their journey(coming to grips with unflattering stuff inside them and others along the way) not the destination(future focus)...they learn to commit to sticking stuff out and following thru and can take pride in what they have genuinely accomplished in life(as opposed to doing the minimum to get by)...they can finally escape from chasing their tail. Only then can they find true satisfaction.
