A harvest in itself. It is wrong just to measure harvests in pounds and pence as not everyone is doing it to keep the mortgage paid.
Monetary returns give the 'Standard of living' rewards.
Pleasure in what you do gives the 'Quality of life' rewards.
They are equally valid.
However the thread WAS about making a living. It can be done but expect to really thrash your body in the key months. The bees ALWAYS have to come first in season.
I regard myself as one of the luckiest people around as I am privileged enough to make my living doing what I love, and if I get spare time I just want to go and do more bees. You cannot get anywhere in this game without really enjoying doing bees and devoting yourself to their welfare. This point is often lost on amateurs, especially the new and easily lead, hearing about the 'evils' of greedy commercial beekeepers. They miss the crucial point, we are essentially the same, just some are lucky enough to have it as the day job.
Getting the bees to give more honey, more nucs, anything of their main attributes in fact, is a measure of their health and the care and effort the beekeeper puts in. Migrating them when they need to be, feeding judiciously, watching their health. Those and countless other factors are in your everyday thoughts. Poorly cared for bees rarely give good harvests. Higher crops are not greed, they are the consequence of better husbandry.
FWIW....husbandry includes location selection, floral knowledge, and judicious migration. Not just the stuff you read in the bee books.
