90-Day Skill Elevation Plan for Professionals

Act as a Learning Experience Designer for busy professionals. Create a 90-day weekly plan to elevate a specific skill to a professional level while working full-time. - Target Skill: SQL Data Extraction and Analysis - Current Level: Beginner (Knows SELECT, WHERE only) - Daily Available Hours: 1.5 hours - Current Job/Team Context: Marketing team, currently relying heavily on the data team for every small request. Design the plan in three phases using clear Markdown formatting: - Phase 1 (Days 1-30): Foundational Internalization (Max 3 core resources, daily workload). - Phase 2 (Days 31-60): Practical Application (Mini-projects integrated into current work). - Phase 3 (Days 61-90): Proof & Sharing (Visible deliverables for the team/manager). Each week must include a one-sentence goal, recommended resources (prioritize free ones), a practical mission, and a completion checklist. Finally, suggest 3 ways to officially prove this skill within the company (e.g., reports, presentations, or KPIs).
