Meeting people randomly has really taken a plunge lately, in part due to the pandemic. Offices and co-working spaces are typically fertile grounds for random meetings but less frequented due to work-from-home initiatives.
Sometimes, the people with whom you strike up a conversation on the street or public transport might turn out to be great business connections. You might be one conversation away from meeting someone who knows someone who could provide a breakthrough for your business.
Random meetings are of a dying breed. Most of our (new) connections are artificially brokered through social media.
Say hello every now and then to strangers.
