A recurring topic of conversation I seem to have had lately with people starting out in life/business/career has been should you follow your passion. My answer has been simple. If your passion can pay you a million dollars a year then sure go for it. If not forget it.
This may sound somewhat hard headed and mercenary but like all of us I view the question through the prism of my own experience. When I was much much younger I had the opportunity to be a professional martial artist and like all young people I thought this would be uber cool. You have to remember I grew up in the era of Bruce Lee. However, I had an epiphany one night when I looked at the sorts of cars that those who had been involved in the arts for a long time drove. They were all shitboxes.
Every so often I catch up with people from the old days and I look at what they are doing. It is generally teaching half a dozen people in a church hall and throwing people out of pubs on weekends to make ends meet. Although they refer to chucking dickheads out of pubs as close protection work as if they are the Aga Khans personal bodyguard.
The message what they did when they were young was their passion and they envisaged a lifetime of doing this one thing. They formulated this view without thinking of the long term consequences of that decision.
Martial arts is still one of my passions but know I pay people to let me hit them. I am not paid by people for them to hit me.
