2 weeks ago, I started reading "Fooled by Randomness" by Nassim Taleb.
WOW, It's been mindblowing!
Thanks to @dvassallo 's recommendation.
Inside, there's a part he talks about how to deal with volatility.
Here’s 6 big lessons that are useful in the current market crash:
Lesson #1:
Negative emotions of seeing your stocks drop > Positive emotion from seeing your stocks rise.
"A negative pang is not offset by a positive one...
Some psychologists estimate the negative effect for an average loss to be up to 2.5 the magnitude of a positive one)...
... At the end of every day the dentist will be emotionally drained.
If the unpleasurable minute is worse in reverse pleasure than the pleasurable minute is in pleasure terms, then the dentist incurs a large deficit when examining his performance at a high frequency."
Lesson #2:
When we zoom out and check the prices less frequently, we are less affected by negative emotions.
Because over a longer time horizon, the market tends to rise more than it goes down.
