A lever long enough…
“Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.” — Archimedes
How long does that lever need to be? I suppose it depends on the size of the world you’re wanting to move.
Pick a domain that resonates with your innermost being (maybe it actually picked you?); your principles will serve as the fulcrum; and the rod needed will present itself.
