This goal has the following fine print specified by pjh:
Businesses run on relationships. So do most things.
Every day I will contact somebody that I know or want to know better. Probably by email. Doesn't matter if they reply, I've bumped into their attention sphere.
Serendipity shouldn't count. Bumping into someone on the street isn't a deliberate contact. Yes, that contact might be valuable. Email somebody anyway.
Replies to their emails mostly doesn't count. Replying to something neglected is worth counting, provided of course that this doesn't lead to deliberate neglect…
