Four silent conditions. If they are not met, better not to begin.

i.
Real exposure
To decision, complexity, the solitude of the role. Not an ambition — a load.
ii.
Inner demand
The non-negotiated wish to think better. Not faster, not louder.
iii.
A long horizon
Acceptance of work measured in seasons, never in deliverables.
iv.
A kept word
Respect for the appointment, for confidentiality, for silence when silence is right.

No argument replaces the rightness of a first exchange. The only criterion that matters is verified there.
