Most leadership advice is written for people at the top, deciding direction, or people at the bottom, learning to execute well. The middle gets less attention, even though it's where most working people actually spend most of their career, influencing both up and sideways, with formal authority over neither.
Leading from the middle means two directions of influence happening at once: helping the people above you make better decisions by surfacing what they can't see from where they sit, and helping the people beside you, peers, not reports, move in a coordinated direction without you having any authority to instruct them. Neither of those is about formal power. Both are entirely learnable.
The middle isn't a waiting room before real influence starts. It's often where the most influence actually happens, just not the kind that shows up on an org chart.
Influencing upward from the middle usually looks like translation, taking what's happening on the ground, where you have visibility executives don't, and turning it into something concrete enough for a decision-maker to act on. A senior leader rarely has the bandwidth to notice a slow-forming problem themselves; the person in the middle who names it clearly, with evidence, before it becomes a crisis is doing real leadership work, without needing anyone's permission to do it.
Noticing that a policy rolled out three months ago is quietly causing friction across several teams, and bringing that pattern to leadership with specifics, not as a complaint, but as information they genuinely couldn't see from where they sit.
Influencing sideways looks different, less about information, more about coordination. Peers rarely follow someone because of a title; they follow someone whose judgment they trust and whose asks are clear and reasonable. Becoming the person other teams' managers actually want to align with, because working with you is easy and your word is reliable, is its own form of leadership, built entirely without formal authority over any of them.
Getting three peer teams to agree on a shared process, not by mandating it, but by being the person who took the time to understand each team's actual constraints and proposed something that genuinely worked for all of them, which is a different skill than simply being right.
The middle is also where the cost of getting it wrong in either direction shows up fastest. Leading upward without also respecting your peers' constraints reads as self-promoting. Leading sideways without ever surfacing real information upward means good ground-level insight never reaches the people who could act on it. Doing both, consistently, is what actually defines leading from the middle, and it's available starting now, regardless of what your title says.
