I'm doubting his opinion. Separating joy and profit..
Discussion
On top of my tiny experience ? i would say this ....
An activity that brings you joy and passion doesn't have to be the same one that brings you wealth.
There's no rule saying that the two must go hand-in-hand. Even if they do, there's no guarantee that you'll always experience both joy and profit (with the help of an online translate program)
Joy and passion is a kind of wealth.
And I'd like to enjoy a fiscal profit while also enjoying the process. Not doing so is a compromise and an indicator for improvement.
Or maybe you need to tell me more about why you doubt his opinion.
