I propose we start imagining "social-actualization" at the top of the pyramid. We're moving from an era when "rugged individualism" was foundational to how we defined success to an era when collaboration is essential for both personal and societal success.
While I have experienced -- and want to affirm -- the absolute centrality of letting go, I would like to complicate it somewhat also. Because it matters what you're letting go into -- and that, I think, is actually the harder part of the work.
