After survival comes happiness. There is an argument that what makes us happy is hardwired due to evolutionary programming. If you are not happy

Why happiness?
Happiness is an end in itself, if you ask someone why do you do x? and infinitely regress asking why they do they want what makes them do x, ultimately leads to, “because it makes me happy”…which seems to require no further explanation, because it is an end in itself, you don’t have to explain why you want to be happy.

Much of the research around happiness suggests some of the following as contributing to happiness; enjoying social relationships, help others, express gratitude, be optimistic, eat a healthy diet, exercise, pursue lifelong goals, seek engaging work.

Conveniently these are happiness contributors are broad and major portions of everyday life. Some of the topics such as expressing gratitude and being optimistic could be covered in a semester and reinforced in the other subjects. Other topics such as helping others, pursuing lifelong goals, and seeking engaging work have an infinite number of directions.

Once you progress to seek engaging work it is likely you would naturally need to pursue communication and decision-making as broad skills and students could begin to explore niches that require knowledge of science and business. Again, communication and decision-making are adaptable to the pursuit, some people will want to pursue paths where knowing how to add, subtract, multiply, and divide will be enough, others will want to be physicists. As far as communication, some will want to be salesman where face-to-face interaction is most important, others may want to be novelists and pursue classical prose.

In parallel to all this students should be taught how to learn, learning itself should be taught as a technical skill. How do people complete 17+ years of formal schooling and not be able to provide one authoritative comment on learning theory?
