I've been applying but only sending a few outreach messages. Is that enough?

No. Applications alone — even a high volume of them — are not sufficient at the senior level or for competitive roles. The missing piece for most members is outreach: direct, proactive contact with recruiters, hiring managers, and people in your network who can make introductions. The reality at senior and director-plus levels is that there are fewer open roles and more qualified candidates competing for them. If you're not visible to the people making hiring decisions, your resume may never be seen. Outreach is what creates that visibility. The people getting into multiple loops right now are doing outreach every single day — it is the difference-maker.
