How do you know when to stop tweaking chemistry without overthinking it?

I had a disappointing first try, a surprisingly good second try, and then a third attempt that taught me humility. So, naturally, I now have opinions.

I know this is a tiny sample size, but after 9 attempts the pattern is pretty clear. When I keep the setup simple, I actually follow through.

A useful way to think about it is mechanism first: what changes, what stays constant, and what evidence would distinguish the two. You will learn more from a simple version repeated three times than from a perfect plan you never start.

- Start small and make the next step obvious.
- Keep notes so you can compare what worked.
- Ask someone with recent experience, not just strong opinions.

Come back with what happened; the details will make the next answer better.

Anecdote beats theory here.

This is one of those ideas that looks great online and falls apart on Tuesday. I would write it down before changing anything else.

I laughed, but you are not wrong.

I would ask what outcome you want in two weeks, not in some ideal future. That makes the choice much clearer. That is the kind of detail beginners miss.

Kind of wild how often beginners is the whole issue.

That should give you a solid first pass.

That is a much better way to say it.

Can you expand on that a bit?

Do you think this would work in a smaller place than São Paulo? The 3-minute rule is underrated.

What would you change if you started over? I learned that one the expensive way.

Noted, and thank you.
