It's hard being an optimist in 2016.
After 27 years in prison, Nelson Mandela said:
'Part of being optimistic is keeping one's head pointed toward the sun, one's feet moving forward. There were many dark moments when my faith in humanity was sorely tested, but I would not and could not give myself up to despair.'
Well, if he could stay upbeat, so can we. Science tells us that our intentions alone can affect our physical reality. Whether you call it the Observer Effect, the placebo effect, or simply positive thinking, the very act of vocalising our personal and collective visions for the future can help shape a better one for all of us.
After all the murkiness of the year that's been, and the fear-inducing shadows being cast over our future, it's time for us optimists to step forward - with our head pointed toward the sun - and set out a clear, luminous vision for the next three years. By reflecting on and sharing our dreams, our actions will coalesce. Let's do it.
