My Bottom Line: Ken Olisa, Restoration Partners

Ken Olisa is the chairman of Restoration Partners, a boutique bank.

He regrets failing to follow his own advice to "learn the lesson of the orang-utan"; that is, do not let go of the first branch until securely attached to the second.

Ken appeared on The Bottom Line, which was broadcast on BBC Radio 4, the BBC World Service and the BBC News Channel. You can also download the podcast.
