I used to spend a lot of time stewing about this because as our balance sheet has grown, specifically with land, our ROE and ROA has decreased.  While those are important metrics, and you should strive to maintain a respectable rate for each, at some point you reach a critical mass of assets/wealth where rate of return isn't the most important factor any given day or year.  Idle hands are the devil's workshop, part of me fears that if we were to diversify into more passive investments with higher rates of return it could just lead to more problems, especially for the next generation.  It's well documented that people need adversity and purpose to maintain health, farming affords plenty of both!
