If you have a passion, follow it. It's the best barometer of what you will be good at. And choose a career that you enjoy – the extra money of a job … - Lewis Pugh

I could not believe what I was seeing: everywhere there were whale bones. Thousands of them stacked on top of each other. They rose from the seabed almost to the surface of the water. There were big bones. I could make out many of them: rib bones, jaw bones, vertebrae. In some places they were piled so high that, when I took a stroke, my hands touched them. I thought of all the beautiful whales I’d seen around the coast of South Africa and Norway that add so much to the area. How many whales were hunted and brought to this island before having their carcasses burned for oil and their bones dumped in this way? It disgusted me to such an extent that I considered stopping the swim to move it elsewhere, but I decided I had to press on.

Never plan for victory and defeat in your mind at the same time.

The essence of any great achievement is to believe in your purpose.
