R. Fulghum (1993) contended that all he really needed to know, he learned i
n kindergarten. This finding does not generalize to predoctoral-postdoctora
l education and school-based action researchers. After 20 years, the author
's current aspiration is to collaborate with others to disseminate research
-based social and emotional learning programs that improve the lives of mil
lions of school children. High-quality graduate and postdoctoral training i
nspired this commitment. However, realistically speaking, ongoing early- an
d midcareer training are needed to achieve it. This author describes 2 sets
of advanced learning experiences that strongly affected his current activi
ties. He draws implications from these experiences to encourage age more su
pport for the early- and midcareer training of school-based action research
ers. The address also highlights several priorities that midcareer scientis
ts should address to advance the positive impact that psychology has on the
lives of children.
