The guide gives you the thinking. This makes it real. Pick a decision and work through it — one question at a time.

Because thinking clearly on your own and thinking clearly in a room are different skills. Under pressure, momentum and the cost of looking hesitant push you toward the call you can defend, not the one you believe. Critical thinking for leaders is holding your judgment together when the room wants speed.
Watch for three tells. You accept the first problem named instead of asking whether it's the real one. You choose the defensible option over the one you believe in. You decide fast because the room feels urgent, not because the deadline is. Each one is momentum standing in for thought.
They're three directions from the same refusal to take things at face value. Analytical thinking digs into the detail to find the real problem. Reflective thinking pauses so what you already know can surface. Strategic thinking steps back to ask what's really going on. Most hard decisions need more than one.
Buy the smallest pause. Before you agree, ask what's actually going on here, and whether the obvious answer is the real one. You almost always have more time than the room implies. One deliberate question in the moment beats an hour of clarity afterwards, in the corridor, too late.
Slow down on the diagnosis. The first problem you're handed is usually a symptom, and fixing it feels productive while the real cause keeps working. Ask what the problem actually is before you reach for a solution. The leaders who solve fast often solve the wrong thing.
