I Wish / If Only

"I wish" and "If only" are the two grammar constructions we have been revising 

lately. They are frequent constructions in everyday life according to the number of examples I have found.

Click here to read an article which was published in The Guardian about a year ago called "Top five regrets of the dying." Here is the list of the regrets they refer to. 

Top five regrets of the dying: 1. I wish I’d had the courage to live a life true to myself, not the life others expected of me. 2. I wish I hadn’t worked so hard. 3. I wish I’d had the courage to express my feelings. 4. I wish I had stayed in touch with my friends. 5. I wish that I had let myself be happier.

If you were asked to write a list like this, would you omit anything or include anything else?
