You are the Petty Tyrant
An ambitious right hand who lords over a small kingdom as second-in-command.
What kind of villain
You want to perfectly dominate exactly as far as your hand reaches. Your ambition is real, but the stage is not the world — it's 'my department,' 'my little kingdom,' a hand-sized territory. As a dependable superior's right hand, you set meticulous rules and control your underlings without a gap. The scale is modest but the will to rule is genuine, and your struggle to never let go of small power can be a bit comical. Less frightening than a tyrant sized to a single office.
In everyday life
The moment a role or project lands with you, you master and take hold of everything inside it. You set the rules, tidy the order of things, pin down exactly who should do what. Seeing something others handled carelessly leaves you uneasy, until you end up redoing it cleanly yourself. "Well, this is mine to look after" comes out of you completely naturally — you carry responsibility that readily.

Advice
The way you take firm charge of what's yours gives any team enormous trust and steadiness; the ground you guard always runs without a hitch. But when your control grows too fine-meshed, the people beside you stop thinking for themselves and simply wait for your instructions — and every heavy load ends up piled on you. What if you handed just one thing over today, trusting it completely? It may feel uneasy at first, but even when you loosen your grip a little, the world will keep turning warmly around you.
