To be upfront, there may be a comfortableness with being controlled BUT even more so to have control. This could have come from a controlling upbringing, an unpredictable life, or people in their life who put all the responsibility and authority on them. They are use to structure, LOGIC, rules, things making sense, practicality, maturity, seriousness, and responsibility. Not only does taking care of themselves come naturally but guiding, taking care of, protecting - mostly being responsible for others comes naturally. Emotional suppression can be what they are use to. It feels uncomfortable to express feelings and "burden" others with their worries or problems. OR they could be around people who approach emotions as something highly private and not to be shared. Their natural environment can feel cold at times or even cutthroat. They are most comfortable around the down-to-earth, the level-headed, maybe the crude, the "what you see is what you get", and those that get business done. Ambition, tenacity, their ability to overcome obstacles is a strength. They're use to the harshness of reality, expects something to go wrong, wants to always be prepared. Out of their comfort zone is letting go, relaxing, overcoming negative thoughts and worries.
