Write a Personal Productivity System From Scratch

You have tried GTD, the apps, the time blocking, and they all worked for about a fortnight before collapsing. This designs a minimal, durable system built around your real failure mode and the contexts you juggle, using the tools you already have rather than another shiny app. Something simple enough that you will still be using it next year.

<context>
You have tried [describe systems attempted, e.g. GTD / to-do apps / time blocking / nothing systematic] and none has stuck. Your main failure mode is {PRODUCTIVITY_FAILURE_MODE}. You work across [number] contexts: [e.g. job, side project, personal admin, learning]. Your tools of choice are [describe what you already use].
</context>

<task>
**Design a minimal, durable personal productivity system** built for your specific failure mode:
1. Diagnose why previous systems have not stuck (without self-blame)
2. Define the minimum viable components of a system that addresses your failure mode
3. Select or design the capture, clarify, organise, and review elements
4. Build in a weekly review ritual that takes under 20 minutes
5. Design a 30-day trial protocol with a binary go/no-go decision at the end
</task>

<output_format>
- Failure mode diagnosis (honest, specific)
- Minimum viable system components (bullets)
- System design (one paragraph per: capture, clarify, organise, review)
- Weekly review ritual (step-by-step, time-limited)
- 30-day trial protocol (what to do each week + day-30 evaluation criteria)
