> Some of them are technical, but to be honest a load of them are societal. (as in, bleating like Cassandra and not being able to affect change.)

This is where I am now, where I'm comfortable making technical mistakes and know enough to avoid the most grevious pitfalls, but struggle to expand the sphere of things affected by my changes beyond a few people or single team/product. Some people get into management for this, but I've seen that management is mostly planning, budgeting, hiring/firing, and non-technical communications.
