The best thing I did was walk away from the charts in January. I'm reminded of someone telling me that no one ever says on their deathbed, "Man, I wished I'd paid more attention to the daily news." Either you believe in the long term viability, or you don't. From there, if you scale your bets appropriately and don't have too much money on the line -- you'll sleep fine at night and be able to ignore the noise.
If you truly believe in the long term viability, you put more on the line. Buy the dips.
