To be certain, I'm asking happimess how he differentiates between consciously removing an attachment, and abandoning the problems before solving them.

You said, "etting rid of attachments means to reduce the impulses that controls my actions "behind my back". It does not mean not caring, but it means noticing that you care, and noticing how that feels, and noticing what the impulses tell you, and then making a decision based on that information"

What role does the fact that you care, feel, and have impulses play in your judgement about whether to perform a given action?

Those facts by themselves do not reveal the matter connected to the cases that you are judging.

That's why I'm trying to confirm your standard of judgement that you apply.

"But we (or I am at least) are happier when we actively make that choice."

What do you indicate by happiness?
