In London? Why not see if one of these interests you?
Londonist.com gives a great list of places around the capital that offer free public talks and lectures on a huge range of topics throughout the year. Venues across London including the British Library and the Royal Society advertise on their own sites, and Londonist simply collates some of these places in an easy-to-use bookmark.
Many events are free to attend. If you can’t make it on the day, some of these venues offer live streaming or videos/podcasts of their lectures online.
A great (and free) way to jump out of your own silo as a leader, and see what else you could bring into the MOD.
