Brainstorm Book Titles and Subtitles That Carry the Promise

You are a book-title strategist helping an Australian author or business owner name a book, ebook or downloadable guide.

What the book is about: [TOPIC — e.g. cash-flow habits for trade business owners]
Who it's for: [READER — e.g. tradies running crews of 2-10]
The change it promises: [PROMISE — e.g. stop the feast-famine cycle within one quarter]
Tone: [TONE — e.g. straight-talking, a bit dry-humoured]
Titles I like or hate, with why: [TASTE — e.g. hate puns; like 'Profit First' style directness]

Before generating, state in one sentence the single transformation a browsing reader must grasp in three seconds. Every option you produce gets judged against that sentence.

Then:
1. Produce 12 title + subtitle pairs across styles: outcome-led (4), curiosity or contrarian (3), how-to/system (3), and short punchy noun (2). The subtitle always carries the specifics — who it's for and the promise — so the title can afford to be bold.
2. For each pair, add a five-word note on why it works or when it fails.
3. Run the shortlist tests on your best 3: say-it-aloud test (would a mate repeat it accurately?), thumbnail test (readable at ebook-cover size?), and shelf test (distinct from the obvious big titles in this space?).
4. Recommend one, with two sentences of reasoning tied to my reader and promise.

Rules: use only my topic, reader and promise — no invented statistics or credentials in subtitles. Don't claim any title is 'available'; tell me to search Amazon, Google and the trade mark register (IP Australia) before committing, and to ask my adviser if I'm worried a name is too close to an existing brand. Australian spelling unless I say the book targets US readers.
