Life will have terrible blows, horrible blows, unfair blows. Doesn't matter. And some people recover and others don't. And there I think the attitude of Epictetus is the best. He thought that every mischance in life was an opportunity to behave well. Every mischance in life was an opportunity to learn something and your duty was not to be submerged in self-pity, but to utilize the terrible blow in a constructive fashion.

To launch Canva, we needed investment and a tech team. Finding the right people for both took two years but there is always a lot of rejection for entrepreneurs in their early days. But every time we got a hard question or a reason why people wouldn't invest, we stayed focused on what we could change. I revised our pitch deck after every meeting, more than 100 times in one year, to answer the questions or fix the reason for rejection from the last time. You just have to keep going.

At first the research did not seem to be particularly interesting – I carried out a systematic search for processes that might destroy the CFCs in the lower atmosphere, but nothing appeared to affect them. We knew, however, that they would eventually drift to sufficiently high altitudes to be destroyed by solar radiation. The question was not only what destroys them, but more importantly, what the consequences are.

My dad always told me and my two brothers, “Don’t ever get too proud or too old to say that you love me and to say that you love each other.” “Love” is a pretty commonly used word in our family. When I talk to my brothers now on the phone midday, we always end the conversation saying, “I love you. I love you, bro.”

My dad had such a big influence on me, he was kind of all that wrapped into one. Even if we had a guest speaker at our school, or read something in class, or heard about it, I would always go back and check with him. “Is this right? Would you agree with this, Dad?” He had a big influence on me, so he was the guy I went to for advice and the guy I listened to, and still do today.
