Jouneymen and Masters
As I understand it, everyone who's seriously interested in personal finance should focus on (among other things) making money while they're not doing anything, i.e. passive income. Hugh at Gaping Void put it eloquently:
I try to avoid consulting gigs like the plague.
The thing about consulting I hate is, you just get paid by the billable hour. So the minute you stop tapdancing, you're dead.
A Journeyman gets paid while he works. A Master gets paid while he sleeps.
