There are things you do have control in your life, for example, what you do and how you do it. There are things that you sometimes have control of in your life, such as when you do it. There are things most people don't have control over, such as other people, the weather, etc.
Fear and anxiety often results in controlling behaviors, and rarely results in anyone feeling better. You may win a few battles, but you won't win the war, as one may say. The worst-case scenario is constantly trying to micromanage another person such as a life partner or co-worker, which ultimately destroys the relationship.
People who are highly goal-oriented and duty-bound often "grab the bull by the horns" and are highly productive, and also quite stressed. Myself for example. Passivity is not in my nature. If I want something, I am going to get it, today, tomorrow, the next day, but I will get it. I am not controlling of others, though. That, most of the time, I don't have control over. So, with that, comes a mindset of independence. If I can't depend upon others, just do it myself. Most of the time, I don't even consider help from others. This has been my life from day one.
