Marcus advocates for moving forward despite uncertainty rather than being paralyzed by the lack of perfect information. Doubt and uncertainty are constant companions in human experience - we rarely have complete clarity about outcomes or perfect confidence in our decisions. But waiting for certainty often means waiting forever. The Stoic approach is to act on the best information available, guided by virtue and reason, while accepting that some risk and uncertainty are inevitable. Forward progress comes from seizing opportunities as they arise rather than hesitating until conditions are perfect. This isn't recklessness but rather the courage to act responsibly despite imperfect knowledge.
