I forgot the wetsuit
I found this old picture of me standing next to a canoe. Moments later I would paddle out far far away. It's quite funny looking back at this. At the time I did not think of the consequences going out in low temperature without any gear just a day or two before I had to catch a flight to LAX. When I eventually came back to dry land I became very sick and lost 7 kg in the following days.
What did I learn from this? Always be prepared. No matter if it's in business or in my personal life. When "shit happens" you want to have the right tools.
