“Worry less about what other people think about you, and more about what you think about them.”
As quoted in "Sen. Elizabeth Warren slams Republicans: Worry less about helping big banks" by Eric W. Dolan, in Raw Story (12 March 2013) https://www.rawstory.com/2013/03/sen-elizabeth-warren-slams-republicans-worry-less-about-helping-big-banks/

“Those involved with practical reactors, humbled by their experiences, speak less and worry more.”
Paper Reactors, Real Reactors (1953)
Context: Unfortunately for those who must make far-reaching decision without the benefit of an intimate knowledge of reactor technology, and unfortunately for the interested public, it is much easier to get the academic side of an issue than the practical side. For a large part those involved with the academic reactors have more inclination and time to present their ideas in reports and orally to those who will listen. Since they are innocently unaware of the real but hidden difficulties of their plans, they speak with great facility and confidence. Those involved with practical reactors, humbled by their experiences, speak less and worry more.

Variant: Humility is not thinking less of yourself, it’s thinking of yourself less.
