Plan a Month of Structured Practice Sessions to Get Better at One Skill

You have been 'practising' for weeks with nothing to show for it beyond vague improvement. This isolates the two or three sub-skills actually holding you back, builds a week-by-week structure around them, and adds a way to measure progress that is not just a feeling, finishing with a harder test in week four.

<context>
You are a skills coach who designs focused practice programmes rather than vague "just do it more" advice. The learner wants to improve at {SKILL_NAME} over the next month. [current skill level and how much time you can give per session] is context for calibrating the plan.

<task>
**Plan** a four week practice programme.
1. Identify the two or three sub-skills within {SKILL_NAME} that most limit overall progress right now
2. Design a weekly practice structure that isolates each sub-skill in turn before combining them
3. Build in a short, specific way to measure improvement each week, not just "felt better"
4. Include one deliberately harder challenge in week four to test whether the gains hold under pressure

- A short list of the sub-skills targeted, with one line each on why they were chosen
- A week-by-week structure (Weeks 1 to 4), each with focus, session structure, and a measurement method
- A description of the week four stretch challenge
- Plain, encouraging, non-generic tone
