Could you possibly unpack this for me a little bit? It strikes me as absolutely true for me, too, or at least sounds like it could be true, but I'm pulling at a thread I can't quite grasp.
In the Buddhist philosophy the notion that you can control anything other than yourself is considered absurd. Even conceding that you have control over yourself is being generous. A need for control then becomes a major source of frustration, or as it's often referred to in this context, dissatisfaction or suffering. By studying the philosophy, you gradually untangle the absurdity and you progressively start to see the theory be manifested in reality. You then learn to accept it and see the absurdity of your own desire for control.
I can say that to you and it might make sense. But that's still at the theoretical level. For it to be true to you, you need to make the journey yourself.
Another example is that often people who give up dieting will lose weight and keep it off. What matters is not the calories but the health of the relationship with food, and if the diet is taking an unhealthy relationship and making it even more dysfunctional, then how could it help?
Of course, you found the Buddhist solution which is quite meritorious in its own right and served me well at a difficult time in my life. There is also a Christian mystic solution which has similar aspects.
In addition to that though, I think I (and others?) make sense of the world through narrative and there is value to other people's narratives, though that may be in conflict with the context of your comment.
Trying to find "the best option" or trying to totally control the outcome is counter productive. You lose your options, you lose your time.
While being satisficer you accept some parts that might not be perfect and your life moves forward. You open more options as you are not stuck on picking exactly the right washing machine and you open time and headspace for other avenues.
Imagine leading an animal into a cage with food. To that animal, they are controlling their food intake and their lunch! In that attempt to exert control over the situation they have lost all primary control.
Controlling your thoughts is another matter. Just try to stop thinking for an entire minute. Don't have any thoughts. Alternately, only think about 1 thing. You very probably cannot do it. We don't choose what to think, but we can choose how we react (or not) to our thoughts. You CAN choose to accept the thoughts as they come and not identify with them, deciding "oh, that's a thought, how interesting". This is in opposition to what we normally do, which is to act on every little thought that floats along or decide to 'grab' onto the thoughts and stay with them while going down whatever rabbit hole they lead us into.
Your point does stand, control is a false concept in general.
