Is passion or responsibility more important and why?

No. It depends.

Whichever one you don’t have is more important at the time.

Passion without responsibility gets you nowhere, because you have lots of brilliant ideas and things you long to do, but without responsibility you can’t accomplish any of them. Responsibility without passion gets you nowhere, because you get stuck in a rut and have no goals.

I would think that you should be passionately responsible….

I dunno Boffin, this morning, I’m thinking responsibly passionate sounds a lot more appealing. Maybe even passionate yet responsible. ;-)
