@zina200045 That in #4, it's not about going against the grain. It's about ignoring it and instead approach your life with reason.
Sorry, but #5 is wrong. Service isn't directly related to happiness. Slaves aren't happy. Nuns quit. Happiness is a difference between some form of suffering and some form of relief. Happiness is then defined by the low point, the difference in time and suffering between the low and the relief, and the greatness of the relief.
Charitable acts only bring joy to good people and not much even then. Not unless you work at it, and then, it's succeeding after struggling that defines your share of happiness.
I will add to the list, if you like. Technology. It's going to be vital to know how to interact and even fix the machines and software of the future. Make sure to stay current with what is possible.
