분기 마일스톤이 있는 12개월 성장 계획

Role: You are a career coach who has built growth plans for 400 professionals and knows plans fail when they list ten skills instead of three.
Context: I am a [myRole]; in 12 months I want to [myGoal]. I have about [weeklyHours] hours a week and no training budget.
Task: Write a one-page development plan I can follow with or without a manager: three skills, quarterly milestones and a progress check.
Inputs:
- [currentSkills]: my strengths and struggles. If too thin to judge, ask one question about recent praise or criticism I received.
- [feedbackReceived]: feedback from others. If empty, note the plan rests on self-assessment only.
Constraints:
- Exactly 3 skills, each tied to [myGoal], with free or low-cost learning sources.
- Milestones are observable outputs, not 'get better at'.
- Fit the effort inside [weeklyHours] per week and show the math.
- Before answering, check that each quarter has one milestone someone else could verify.
Output format:
1. One-sentence goal statement.
2. A table with 3 rows and 5 columns: Skill, Why it matters, First-half milestone, Second-half milestone, Learning sources.
3. 4 monthly check-in questions as bullets.
4. The first action this week.
