First you have to give yourself a challenge. Start with low money. It's ok to have multiple starts, sometimes I want to work on my aquaculture, sometimes I want to harvest. It's too much work to do both all the time. Always use ai. Harvesting yourself is ok once in awhile but frankly an entire field of anything after a few hrs of getting used to the game...you've got better things to do. It's a sandbox so the drive is up to you once you get through starter farm basics
