I'd say of all those three number 2 is the most common reason why people don't 'follow their dream', but I don't think it's the main reason.
The main reason, I think, is that it's just real hard to wander off the beaten path. I suspect the primary problem is those first steps and then keeping at it for a while. We are taught from very early on, especially if our parents were 'normal' middle-class people, to do the 'normal' thing.
But based on my interactions with people who 'do their own thing', it seems quite feasible, and often a good recipe for happiness, and not so hard to keep up once you've done it for a while.
