I’m somehow not convinced with this idea. Passion is something that identifies you, IMO. You could have multiple passions, no harm. But eventually you’ll reach a level in your passion that you and your passion will be one. It becomes a part of your life. Any life-altering decision you take, you will think about how it’d affect your passion.
Again, this is just how I feel. I think it’s subjective, and just wanted to respond with this.
PS: I don’t know if this will go as a private note. :D
