Now the reason I tell you this is not because I am looking to impress you, or to request that you donate money to charity, or anything like that. No, the reason I mention this is because 3 1/2 years ago when I decided to run my first marathon my two best friends told me, "you're too fat, you're too old, you're too unfit, why not try something easy like a 10k".
And I have to say they were not alone in their thinking, many others said the exact same thing. I'd even thought it myself, and it was this thinking which had stopped me from even trying.
But doubts, whether they are our own or those of others, are the things that stop us from reaching our full potential.
No one, not even me would have thought that I had 10 marathons in me. I thought at best I would be one and done.
But yet here I am, I have run over 3800km in training, I've completed 9 marathons and will make that double figures by midday on Sunday.
We are all capable of so much more than we ever dare dream, and it doesn't always take great talent either. I say that because in spite of the achievement I am not a great runner, I am not even a good runner, I just set the goal and then was persist and consistent, and surprised everyone myself included.
My wish for everyone in 2016 is that they can look to achieve something amazing, their equivalent of running a marathon.
So dream big, ignore the doubts, and go for it.
My marathon journey started with a 15 minute run, it was a only a small step, but it's small steps that accumulate very quickly to become big achievements.
To further illustrate this point, i started writing at the same time as i started running, and now I have written over 800 leadership articles, I've published 3 books and been accepted as a contributor on some amazing platforms.
I don't see myself as a great writer, but i am prolific, writing 3-4 articles per week, and its this persistency and consistency which has helped me gain visibility and I would say exceed my writing potential.
Don't tell me you don't have the time either, that was the excuse I used before I started running and writing, but that's just a case of us prioritising other things ahead of our goals and our dreams.
Don't do that, it only leads to regret!
Everybody has the same 24 hours a day. Some of us, like me didn't make the best of that time, others such as Barbara Cartland used it very productively writing over 23 novels in a single year which is the Guinness World Record, and 720 books in her career.
So I give you the challenge dream big, ignore the doubts, starts small, be persistent and consistent and if you do that maybe you will achieve an amazing goal.
