Ambitious leaders are often "time optimists," underestimating constraints. This leads to frustration. The 'realistic optimist' framework resolves this tension by holding two ideas at once: an optimistic, forward-looking vision for the future, and a realistic, grounded assessment of present-day constraints like time and resources.

For leader Mo, her impatience stemmed from viewing her role as the "final chapter" of her career. Recognizing this reframed her goal from "completing the work before I leave" to "ensuring the work has lasting impact after I'm gone."

Success at the leadership level requires a developed tolerance for pressure and uncertainty—a skill the CEO calls a 'stomach' for it.
