I have been there so often already:
Met someone super intersting on an event, had discussions about topics that we both find exciting, exchanged linkedin/whatsapp contacts.
Who can guess what happens next?
- i lost the connection under all the other ones i made that evening
- i basically forgot to follow up and the contact went out of sight (typical whatsapp issue)
- i forgot the topic we discussed and therefore was unsure if i shuold still follow up
- i followed up and we had nice discussions, coffee or even worked on a collaborative project or established some kind of synergy
