I think by, "Work with better clients", Patrick really means, "Stop doing work for cheap clients". I agree with him that payment from clients in the 5-digit range tends to go much smoother than from those at the bottom of the barrel.
I would also add that, when you charge a higher rate, you also can justify higher initial deposits and milestone payments along the way. This gives your client more "Skin in the game" which makes them more likely to honor the contract terms so that they can receive the final deliverable.
When I first started doing freelance development I made a practice of undercutting everyone else to get the gigs. This did earn me a fair supplemental income, but it was not a business model as clients at this level (<$1k) tend to have very little vendor loyalty and will just move on to the next cheap provider when you eventually try to raise your rates. Since restricting myself to projects of $5k or above things have gone much smoother and I'm alot happier.
