The flaw in, say, austerity, is that its success is predicated on the relative exactitude of math rather than the shifting, liquid imperfection of people's lives.
The fundamental flaw in Social Security and Medicare is that they violate the 'welfare principle' in economics. The welfare principle forms the fundamental basis of all charitable work in churches and other private organizations: assist those who need help, and equally important, don't assist individuals who can take care of themselves.
I think my biggest flaw is my insecurity. I'm terribly insecure. I'm plagued with insecurities 24/7.
Better a diamond with a flaw than a pebble without.
A monomaniac is a sick person whose mentality is perfectly healthy in all respects but one; he has a single flaw, clearly localized. At times, for example, he has an unreasonable and absurd desire to drink or steal or use abusive language; but all his other acts and all his other thoughts are strictly correct.
All creatures are flawed, but out of the flaw may come the universe.
It's always more interesting to take on someone that's going to have hidden sides or a fatal flaw, because there's going to be more to play with - more conflict, internally or in and around them - but it's probably the thing of finding the positive in there.
I like the fact that in ancient Chinese art the great painters always included a deliberate flaw in their work: human creation is never perfect.
Lordy, lordy, lordy do I love money. It is a character flaw, no doubt, one that springs from a panicked childhood in which I always felt as if our family was only a couple missed child support payments from being tossed onto the pitiless streets of our suburban New Jersey town.
I believe the most intricate plot won't matter much to readers if they don't care about the characters, especially in a series. So I try to focus hard on making each character, whether villain or hero, have an interesting flaw that readers can relate to.
