Seems his list was missing an important one: Not playing the victim.

Yes, sometimes other people will cause you harm. Could you have avoided it, probably not as you can't always predict the future.

How you move on from a bad situation is your decision. Wallowing in self-pity because the world has done you wrong is a good way to never succeed.

As an aside: your chances of getting a particular cancer can be affected by your lifestyle choices so you can make better decisions to avoid it.
