There are different kinds of smart. There are those who are book smart and those who are common sense smart. You can have both, but usually we associate book smart with smart.

Those without the common sense part seem to be unhappy. They just don't get what life is about because it isn't written out for them somewhere. There is no formal process for being happy. And it is a journey not something you do once or twice and then you have it forever.

I'll take common sense over book smart any day. Those folks get it and realize life is a true journey. At each step you need to take stock of what is happening and make good choices. And happiness is achieved by dealing and moving on. Not looking in a book for when and how they will be happy.
