Fill the grid with people you've interacted with directly (people in your more immediate network). Managers current and former, colleagues, mentors, the people you mentored, funders and partners, the person you met once and vibed with - all these are possible connections to tap into.
Assign an ask to each name. "Catch up" is not an ask. Be specific with yourself about why you might want to connect. Nothing you type leaves your browser; it saves on this device as you go.
Star one to three squares above. Three is enough to build momentum and few enough that you'll actually do it. Bring these to your breakout, along with the part you're hesitant about.
