It surely helps, but is this true? I don't really see how something like that could be verified.
The implication is not a good one, either. What is one without passion do, just give up? Doesn't seem to be terribly helpful thinking, especially since it's not clear where passions come from or how they develop.
Passion comes from having interest. Interest comes from noticing particular facets about something that amuse you, perhaps because they are mysterious or perhaps because they give you pleasure. So if you want to become passionate about something, search for aspects about it that amuse you and focus on those things. That's not the whole story, but it's a start. It's worked for me at least.
