Anyway you look at it, beliefs about stabilising the core in order to get strong, protect the spine and have a good posture are rampant among friends, in communities, in society and in the media. Why on earth wouldn't you follow advice that appears to be endorsed by everyone, everywhere?
Have you ever been in such a difficult situation that you've not known what to do or where to turn? Sometimes life can present us with these situations that really test us on every level, causing us to find within ourselves everything we have in order to overcome them.
Just as vulnerability is helpful in the right doses, so is failure.
I have to admit, in the short term this can be an effective way to overcome a fear: saying things to yourself such as 'come on you wuss!' or 'even a 5 year old can do this!' can give you that quick boost in fearlessness which can give you the courage to go out and tackle the fear temporarily.
It's so easy to stay settled in our comfort zone waiting for 'someone' to come along and tell us it's OK to leave. Only we can give ourselves that permission. We can quieten that voice in our heads that says "you're not allowed to do that' and shout back: "Actually I am!"
The other day I took my daughter to feed the ducks. I say ducks, but really they were swans, big, hungry, strong-looking swans. My daughter is tiny, the swans were bigger than her.
Basically as you get older, you realise that you are not the only person in the world who worries about things. Everyone is riddled with insecurities, they just manifest them in different ways, or if they are really lucky, they have learned to overcome their difficulties (I recently re-read M Scott Peck's The Road Less Travelled and it was brilliant on this subject).
I am currently conducting a survey into confidence and one of the things I'm interested in is the way a person's body is when they lack confidence. They tend to slump, they withdraw physically, their head drops and their eyes look away.
Before I became a mum, I thought I knew what fear was. I believed I had felt it and experienced its debilitating force. I now know I was wrong. I would give anything to go back to the time when my biggest fear was sleeping through my alarm and arriving late for work. Or forgetting to pay my landlord his rent on time.
For many of us in Team SCA, that life-defining moment has been being part of the Volvo Ocean Race...
