Being a good systems thinker makes you a worse operator.

You can understand ambiguity abstractly and still get totally frozen by it in practice.

Operators who are too smart can't operate.

You need to be able to turn part of your brain off (the doubts, the "but what about...") and do a thing that others can believe in.

If your brain is constantly pointing out the indirect effects of each decision you'll be frozen and can't move.

You have to be able to move, even though you know it's not perfect.
