I actually have two favorites here:
dynamics and people.
I admire how our industry keeps evolving
and adjusting to cover users' needs
to better serve purpose and learn as it moves along.
And it's learning opportunities
that also bring the people together around common goals
and around mentoring or being mentored
or having a voice and fostering a team.
I think tech is one of the domains
that relies mostly on teamwork,
and that is particularly meaningful to me.
