By taking our cues from professional changemakers -- we are well positioned to build our own platforms in our own communities at little or no financial cost. 

Uri Treisman, a Calculus instructor at UC Berkeley, wiped out the mathematics achievement gap between his Latinx and Black students on one side and the Asian and European American students on the other side through the creation of his own platform, study groups. ​​ Let's consider him a role model.  And his idea costs very little money to replicate.  
 
JB Schramm, a youth worker in Washington, D.C., realized that many of the young people he got to know did not score well on standardized college entrance tests.  So he built his own platform, a program to help them write their college essays.  Let's consider him a role model of ingenuity. And his idea costs not much more than time.
