FOLLOW PASSION vs CHASE SUCCESS
In simple terms, the Passion Follower does what he (or she) does because it brings purpose or meaning into their lives and they enjoy it! As Wayne Dyer put it, "Doing what you love is the cornerstone of having abundance in your life."
The Success Chaser chooses jobs, careers, opportunities (and more) based on the pursuit of money, wealth, prestige, status symbols - "success" as it has come to be known in our society.
These paths are not mutually exclusive of course... Ever met someone who loved money so much they made a lot of it? Did you like them? Probably not - but there's no doubt they were passionate (about money) and successful (rich.)
The better way to combine these paths (in my opinion) is to find that thing that you LOVE to do and feel fulfilled by. Work starts to feel a lot more like play, and (just like in school) we all tend to do better at the things we enjoy. Most of the world's truly successful people have been driven by passion - wealth has been a byproduct.
AND... if wild "success" never comes, and you live a modest life unadorned by sports cars, yachts and private jets, you will have at least lived that life doing something you enjoyed!
