The problem of OpenAI is that they try to do everything, which is almost impossible.

Brain dump all your thoughts on a piece of paper. Clear your mind.

Creating a game is not as easy as I thought. It’s not just technical, but also an art of how to make it fun to play.

Shopify just changed how you can query the backend admin data from Jan 1st 2026. Great!
This is which vibe coding sucks because you have to actually read the documentation to know why the old way doesn’t work. Took me 3 hours to realize.

Setup Firebase scaffold function to validate Shopify HMAC. If valid, process request body.
Feeling good!

Spent a lot of time on the design of the overall flow. Especially trying to figure out how to integrate Shopify with my Firebase functions.
My design process includes describing my overall business requirements to AI. Then refine the details for each step. Finally ask AI to summarize the overall process and give me the prompts for each technical step.
How do you design your app?

A lot of messes is still waiting for me to clean up. But, there is no perfect moment to build. I must keep going and do the clean up on the way.

Day 12: Idea’s validated (sort of)
Now I learned that there’s demand for my product. And I know how to target my potential customers. I’m ready to build the actual business and automation pipeline.
The problem is, the acquisition cost is quite high compared to my target selling price.
How do I lower the acquisition cost?

Random thought:
What’s the breakeven point of buying all the Powerball combos?
The break even point of the Powerball is about $584.4M to buy all the Powerball combos.
The lump sum after tax of the jackpot is ≈$30% of the advertised jackpot
If the jackpot is $2B and you’re the only winner, you can make $16M. If there’s one other winner(or more) you’re losing money.
In conclusion: not worth it

Do nothing as ChatGPT suggested.
Got a total of 5 signups since the new campaign started. Guess I just need to be patient.

Day 8:
Created new search campaign, the ad is getting traffic again.
I was getting impressions but no conversion. Eventually the campaign just stopped getting traffic at all.
The problem was that I was using a gtag from a Google analytics account and a gtag from the ad campaign to track users. So they’re fighting each other.
Also I added a call in the thank you page so the conversation can be properly tracked.

Stay disciplined. I’m not building anything until I validate my idea. It’s painful but I think this is the way.
