Well, I don't have much to say as regards this as purpose should be individualised.
The most important thing to me is doing what makes you happy at the end of the day.
What is life when you are not happy?
The major thing is to live a life of purpose.
What happens if what akes you happy today, harms you tomorrow?
I know parents who make their kids happy daily by feeding them what they enjoy eating. I think they are setting their children up for a life of mostly misery.
That's why I said end of the day and End of the day for me means long term
