Yea. Local circumstances would differ greatly. However, it's easier to pursue passion when ones personal circumstances is right for that.
A good example are open source software projects.
Open source software projects are usually a result of people's passion. But look closely, most open source software projects are born in advanced and developed countries were people don't worry about basic necessities as much compared to underdeveloped countries.
Hmmm true! I see your point.
The truth is, choosing money over passion is something we will enjoy for a little while because we are not really adding value to ourselves but someone who is following his or her passion.
I believe that as long as you have a passion and you keep improving on it, you will get wealth, not just money. Yes, even in Nigeria!
