## Summary

On day two of a self‑imposed 365‑day AI challenge, the author upgraded to the paid $20/month plans for both ChatGPT and Claude after hitting the limits of the free tiers while trying to create LINE stickers. The subscription was framed as a self‑investment rather than a waste, allowing unrestricted generation and modification of images.

With the paid access, the author produced multiple sticker concepts, repeatedly tweaking prompts after each unsatisfactory output. The experience highlighted that vague instructions lead to off‑target images and that asking the AI itself for prompt‑building advice can dramatically cut the number of iterations needed. After refining the prompts, a complete sticker set was assembled and submitted to LINE for review, though no sales have occurred yet and revenue remains at 0 yen, leaving the author in a negative balance due to the subscription fees.

The writer concludes that AI is not a magic button; mastering prompt engineering and being willing to invest in the right tools are crucial for small creators aiming to monetize generative AI outputs.

## Key points

- Subscribed to ChatGPT and Claude paid $20/month each to overcome free‑plan limits.
- Repeatedly refined prompts to generate LINE sticker images, discovering prompt specificity is crucial.
- Finished the sticker set, submitted it for LINE review, and still has 0 yen revenue after paying subscriptions.

## Why it matters

Shows that modest paid AI subscriptions can be essential for creators, and that effective prompt engineering is a key skill for small businesses using generative AI to produce marketable assets.
