In relation to the principle that all men are created equal, let it be as nearly reached as we can. If we cannot give freedom to every creature, let us do nothing that will impose slavery upon any other creature. — 1858

My Take – You can’t help everyone.  There is a finite amount of time, effort, treasure, sweat, and blood that can be expended on any goal, no matter how noble or important.  But the only way to optimize the use of those resources is to make sure that you aren’t doing something that makes the job harder, or worse, reverses any gains.
