Some of the best connections I have made have come ‘out of the blue’, for example by people emailing me from across the globe in response to the information on my website. I can think of several of these which have led to me meeting and working with some amazing people, for example in China, Singapore, Africa and Europe.
Other great connections have come from meeting people at conferences and on projects. It’s odd, but often the best connections come when you least expect them, and not from the obvious directions - at the train station after the meeting has finished, or with someone you initially didn’t like. I can’t decide which is my ‘best’ connection, but often the best ones are the most unexpected ones.
