What does this quote mean?

“Activity does not consist in velocity of change but in constancy of purpose.”

Being busy or changing quickly is not the same as purposeful action; continuity of aim gives activity its direction.

Source note: The Life of Reason; the line appears in Santayana’s analysis of ideas, activity, and sustained direction.

“First, do nothing inconsiderately, nor without a purpose.”

Deliberate action begins by knowing why an act is being done instead of moving from impulse, distraction, or social pressure.

Source note: Meditations, Book XII, section 20, George Long translation.

“Self-help is the best help.”

Asking for help does not replace the responsibility to make the effort that is already within one’s own power.

Source note: Moral printed after “Hercules and the Wagoner” in the Townsend translation; Hercules first tells the driver to help himself.

“Here is my work, here or nowhere.”

Carlyle’s imagined capable leader locates responsibility in the actual sphere available to him rather than waiting for a more convenient setting in which to act.

Source note: Latter-Day Pamphlets, No. IV “The New Downing Street”; Project Gutenberg #1140. The sentence occurs inside Carlyle’s controversial political argument about leadership; this collection uses it for work/responsibility while retaining that historical context.

“Well done is better than well said.”

Franklin gives execution priority over impressive promises or intentions.

Source note: Poor Richard’s Almanack.

“Wisely and slow; they stumble that run fast.”

Speed without judgment can undermine the very goal a person is pursuing, so patience becomes part of effective action.

Source note: Act 2, Scene 3; Friar Laurence urges Romeo to move with greater care.
