Seeds not planted or tended by choice tend to be weeds, so at least for me, it's very helpful to consciously and periodically choose which seeds I want to water, and to think through what I expect to happen from that watering. Investors can spend a lot of time and energy reacting to the latest bits of news and trying to predict the next surprise, rather than choosing a consistent set of daily actions that they can carry out as things develop, regardless of how they develop.
