"Stepping outside your comfort zone is supposed to feel uncomfortable because we're in new and unfamiliar territory. Being uncomfortable is a sign of success, NOT of failure! So if we are uncomfortably outside our comfort zones, then than means we are growing!!! And THAT is cause for celebration!" (modified from a passage in Roz Savage's "Rowing the Atlantic")

My advice is don't keep asking yourself if you can do something. Just get out there and do it. You can really surprise yourself.

I have learned to acknowledge and appreciate the 98% that I have achieved instead of the 2% that I didn't.

So let's raise the tone of the debate. Too often at the moment we look like schoolchildren squabbling over a toy - our most precious toy, the Earth. And the danger is that as we pull in opposite directions in our global tug of war, the Earth will end up broken - or at least unable to sustain human life. That is the worst case scenario - or maybe, from the Earth's point of view, the best.

Like riding a bike for the first time, sometimes you just have to go for it. If you keep looking forwards and maintain your momentum, it will probably go well. But if you start to doubt yourself and look back, you are more likely to suffer a major wobble followed by a crash.

I'm not claiming to be anything out of the ordinary. I am not especially big or strong or brave or intrepid.

I am a rolling stone, never in one place for very long.
