In one way Hapiness can be viewed as a simple choise, and that includes then doing things that makes you happen like you listed here, But is happiness a goal in and of itslef?

Isnt it better to have fulfilment in a life purpus as a goale? Not that finding you own purpus based in what excites you is easy. But if you do, then Happyness isnt even a question as you are automatically happy when you are on that path.

And isnt that a better place to start? Finding what excites you that is filled with purpus. And then i mean something that gives value to both you and others around you. Otherwise its nothing but pleasing your negative ego.

And this is where Philosophy truly is the tool of choise in my opinion :) As it includes self reflection.
