Nobody made a greater mistake than he who did nothing because he could do only a little.

Small contributions get dismissed by the very people best placed to make them, because measured against the size of the problem they look pointless. That comparison is the error. Large problems are rarely solved by one large act, and a great many little ones are how most real change has happened. Doing nothing feels like modesty but amounts to deciding that the little you could offer was worth less than zero.

Pick a problem that overwhelms you and find the smallest honest thing within reach, a donation, a letter, an hour. Do it without asking whether it is enough, since that question is the one that stops people.
