It's awesome to have what you love and good at being one of the biggest growth sectors when you starting out.
Though I would still be happy to do what I love even if it just made me a decent living and can't make me a billionaire.
I think where most people get caught is that they want to do what they love and they want it to make them billions. That's not always possible.
It's almost very likely that you have some skill that you enjoy doing that can make you happy and a good living. If it makes you Billions great, but if it doesn't than you'll still be happy which is not a bad deal.
