Not a bad idea, but NOT NECESSARY. I find purchasing a high end instrument to be incentive to work through the tough stuff because of the money already spent.I'm just saying I'm aware of issues with goats the OP may not be. In any case, it's not a bad idea to try something on a smaller scale before making a major investment. I rented a paddle board a few times before buying a high-end one of my own after learning I enjoyed it (despite a massive fear of water).
Many people like chickens. There are people who have chickens for pets, even have them in their houses. If someone purchases chickens and sets up the whole shebang (I've raised chickens too), that person has more invested in making it work out somehow and not just dropping the project because of one bad experience.I thought I would like owning chickens because I like fresh eggs. I discovered I don't like being pecked on my hands or ankles or the smell of the #$&% beasts. They are EVIL. So glad I didn't spend $5,000 beforehand getting setup to own chickens.
Your experiences are valid. Others may have different experiences.
If I didn't know better, I would think you were someone who never took any risks. You take risks; the ones you want to take. The OP may want to take different risks, which might include not reading up on something ahead of time.
