Quote from Lamont_C:
Intelligence is only part of it. Being thick-skulled is also an issue. So many of the "intelligent" think that they're smarter than the market, smarter than the books they've skimmed, smarter than all those losers that everybody is always talking about. Therefore, they don't have to do the work. They don't have to pay their dues. They don't have to slog through the process like everybody else. They are, after all, smart.
Intelligence and humility. Now there's a killer combination for you.
