Ben Jealous head of NAACP seems super-competent & successful- Why would he leave position?

[astro]

This guyappears to be hitting it out of the park and as head of the NAACP is (I would think) king of the mountain in his chosen field. There appears to be no whisper of scandal. Why in the world would he give this up? All the stuff below re academia and heading a PAC is great but it would seem to pale in comparison to being head of the NAACP.

NAACP President Ben Jealous to Step Down This Year

In a written statement Sunday, Jealous, now 40, said he plans to pursue teaching at a university and wants to spend time with his young family.

“The NAACP has always been the largest civil rights organization in the streets, and today it is also the largest civil rights organization online, on mobile and at the ballot box too,” Jealous said. “I am proud to leave the association financially sound, sustainable, focused, and more powerful than ever.”

Jealous plans to step down on Dec. 31. His departure plans were first reported by USA Today.

Jealous told the newspaper he also plans to start a political action committee to raise money to elect diverse progressive candidates to public office, though not necessarily only Democrats. During President Barack Obama’s first campaign, Jealous said he teamed with others to create a fundraising group that raised $10 million to help elect the first black president.
