Disclaimer: farming is not a hobby and you need expertise in a broad range of fields, including chemical, technical, administrative. And the job has a high failure rate (if you don't have the expertise) and death rate (big machines and chemical processes).
one for machines, a half to handle them without losing an arm, another half to repair what you can, one for pestcontrol/fertilisation, one to handle silage/muck without dying or burning your barn, one not to get a fine for missing a law...
And one for all the equipment that broke halfway through harvest and you have to fix but ended up replacing to finish harvesting and is now effectively an equipment graveyard
Part of the senior dream is you have funds to carry you.
My version of the senior dream is to "phase out" of the industry, taking on more bespoke, white label projects, eventually support and advisory roles, as my real life restarts, away from the computer.
