Doing what you like is freedom. Liking what you do is happiness. The solution to the problem the Buddhists wisely identified as “dukkha.”
Freedom is insufficient to provide happiness to most people, because they are unprepared to be happy within the conditions of human existence. The next thing you want or must have will not provide happiness, any more than the last one did. This, by the way, is the opposite of the lesson that commercial television is employed to teach you. That sells freedom, or rather the illusion of freedom.
