" The next morning I would be returned to camp with the others who hadn’t made the grade. I was totally dejected.

That night in those woods, warm and dry under my shelter, blisters attended to, dry socks on, and out of the wind and rain, I learnt an enduring lesson: warm and dry doesn’t mean fulfilled and happy.

Only a few hours earlier I had been longing to be warm and dry and safe. Yet lying there, knowing that my buddies were starting out on a grueling night march without me, was pure agony. Never has anyone wanted to be cold, wet and tired as much as I did right then. And never have the comforts of shelter and food meant so little to me.

You see, being dry and warm in life, but with no purpose, is no consolation for being in the heat of the arena in pursuit of your goals.

Don’t get me wrong, warm and dry is great as a reward ‘afterwards’, and we should all regularly enjoy some time chilling, doing ‘nothing’ - but if all you do is ‘nothing’, you will find it a very hollow existence.

(So yes, I went back on the next Selection course and went through those 11 months of SAS hell again - and I passed. I was cold, wet and exhausted throughout, so that now, when I relax, I feel that huge sense of pride for having endured.)

Once you commit to your goal, don’t get swayed by the temporary lure of creature comforts and easy feelings - instead, keep focused, and remember the pain never lasts for ever, but the pride in having followed your calling will. "
