Here are some quotes:
It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat. — Theodore Roosevelt, Citizenship in a Republic, April 23, 1910
Just because you fall on your ass doesn't mean you need to stay there. — Hughie, The Boys, S01E01 - “The Name of the Game”
As a single footstep will not make a path on the earth, so a single thought will not make a pathway in the mind. To make a deep physical path, we walk again and again. To make a deep mental path, we must think over and over the kind of thoughts we wish to dominate our lives. — Wilfred Arlan Peterson, The Art of Living, Day by Day: Three Hundred and Sixty-five Thoughts, Ideas, Ideals, Experiences, Adventures, Inspirations, to Enrich Your Life, (New York: Simon and Schuster, 1972) p. 77
less, but better. — Dieter Rams
It's easier to hold your principles 100 percent of the time than it is to hold them 98 percent of the time. — Clayton Christensen, Harvard Business School professor
Once you simplify the tooling & get deeper into the characteristics & capabilities of each tool, you begin to get more precision in your results. by focusing on a tool you find what it will do & how it does it but more important, how your action augments, modulates, or negates its performance. If you use it enough & your observation-sensitivity is operational, you will end by being able to do things with the tool which will surprise & amaze you.
You don't have to be a zen master to recognize that this will result in some pretty peachy changes in your relationship with self & thus with the rest of the universe. — Ken Isaacs, on working with simple tools
