@reddogaustin I thoroughly agree with this. Personally, it has been one of the toughest things I've had to work on over the years.
Slow thinking is all about the process of identifying what you want to invest in (and not), your thesis, valuation, entry point, and exit criteria. However, sometimes the market presents opportunities to enter or exit at a favourable price and here you have to engage both "fast" and "slow" thinking together.
With all the noise in the market on a day-to-day basis, its really easy to get sucked into a fast thinking, reactive mode as a default.
Kahneman's work is amazing, and a great resource for life and certainly for investing. A worthy Nobel Laureate.
