I was writing in my investing journal last night and came to the realization that this latest downturn in the market has catalyzed a shift in my mindset over the past few months.

Where I once measured my portfolio and positions within it based on dollar value, I've now come to rely on number of shares as my measuring stick. In a time where week after week my position's dollar value has declined, despite my ownership or "piece of the pie" increasing, this has been quite helpful.

Whether this change is a sign of growth as an investor, or simply a tactic to preserve my sanity while allowing me to continue to set emotions aside and buy great companies on sale, I do not know. Sharing in case this might be of use to anyone else in their journey.
