For both partners: make a formal, explicit agreement that the relationship is the most important thing either of you will build. Write it down if that helps — it is consistent with how both of you think. Then review it regularly, with the same seriousness you bring to any major project review. Are both partners getting what they need? Is the relationship growing, or just enduring? Where does it need investment?
Also practice receiving. Two 22s are extraordinary at giving — at building, providing, achieving, contributing. Both can find it genuinely difficult to receive — appreciation, support, vulnerability, rest. Practice being the one who is cared for, not always the one who cares. Let your partner see your doubt, your exhaustion, your ordinary humanity alongside your extraordinary capability. That is not weakness. That is the foundation of genuine intimacy, and without it, even the most impressive structure remains, in some essential way, empty.
