Build a Long-Term Musical Development Plan

You have years on the instrument and a vague sense of wanting to get better, but no actual plan. This sets out a three to five year development path tied to your real goals, whether that is gigging, recording, or just playing well for your own pleasure. It targets your biggest unresolved weakness instead of letting you drift.

<context>
You have been playing {INSTRUMENT} for {YEARS_PLAYING} years. Your current level is [describe honestly]. Your musical goals for the next 3-5 years are [describe: e.g. perform live / record an album / reach a professional standard / play purely for enjoyment at a higher level]. Your biggest unresolved technical weakness is [describe].

<task>
**Design a long-term musical development plan** that serves your goals without treating music like a job:
1. Define what 'good enough' looks like for your stated goals, not perfection
2. Identify the 3-4 developmental areas most important to your goals (technique, theory, ear, repertoire, ensemble, composition)
3. Design a sustainable long-term practice architecture: hours per week, seasonal variation, and permission to plateau
4. Plan for skill preservation vs skill development: how to maintain what you have while building something new
5. Design a 5-year milestone arc (not rigid targets, but directional markers)
