Me : It is important to at least aim to be happy. This can be via contentment or what you do or a mix of both.
X : So, do what makes you happy?
Me : As much as possible.
X : What if it doesn't make you happy.
Me : Then do something else.
Me : Of course, if it's within your power to do so. But if it was then you'd have already done that. Probably.
X : So, just do something else?
Me : That sounds a pretty reasonable assumption.
X : Why probably?
