One of the people I follow on Twitter, @benhollebon posted a link to this video earlier with the simple title 'Thought Provoking'. It's not a short YouTube clip, but it does match the title. It's a really simple video asking some really big questions about life, one of my favourite 'What motivates you - love or fear?'
I'm still thinking about how I would answer all of them, perhaps I'll run a blog series on them after my dissertation has been handed in. In the mean time have a think yourself... what motivates you in life? Love or Fear?
