プロンプト
SMART基準に沿った目標を設定する
I have a goal but it's not specific enough to act on. Vague goal: [describe what you want to achieve] Timeline: [when you want to achieve it by] Why this matters: [your motivation] Resources available: [time, money, support] Past attempts: [what you've tried before and why it didn't work] Transform this into: 1. A SMART goal statement (Specific, Measurable, Achievable, Relevant, Time-bound) 2. 3 lead indicators to track weekly (actions you control) 3. 1 lag indicator to track monthly (the outcome you want) 4. The first 3 actions to take this week 5. A 'minimum viable' version of the goal if circumstances change 6. An accountability check-in schedule with specific questions to answer

プロのコツ
「もっと健康になる」ではなく「3ヶ月以内に週3回30分のジョギングを継続する」のように具体的に。AIは曖昧な入力から具体的な出力を生成してくれます。
四半期の計画を立てる
Help me plan my next 90 days. Life areas to focus on: [career, health, relationships, finances, learning, etc.] Biggest priority this quarter: [the one thing that matters most] Ongoing commitments: [work hours, family, obligations] Energy level: [high / recovering / building back up] Last quarter results: [what you accomplished and what fell short] Create: 1. 3 quarterly goals (no more — focus beats volume) 2. Monthly milestones for each goal 3. Weekly habits that compound toward each goal 4. A 'not doing' list: what to deliberately deprioritize 5. A mid-quarter review template for week 6 6. A reward system for hitting milestones
最適な用途: GEMINI
Geminiは最も構造化された四半期計画を作成し、目標、マイルストーン、レビューポイントが明確に配置されています。
テスト済み Feb 15, 2026
プロのコツ
四半期に3つ以下の主要目標に絞りましょう。5つ以上の目標はどれも十分に達成できない結果になりがちです。
アカウンタビリティシステムを構築する
I struggle with following through on goals. Help me build an accountability system. Goals I'm working on: [list 2-3 current goals] Where I usually fall off: [what breaks your momentum] Social support: [accountability partner / group / solo] Tools I use: [apps, journals, spreadsheets] Motivation style: [reward-driven / consequence-driven / progress-driven] Design: 1. A daily check-in routine (under 5 minutes) 2. A weekly review template with honest self-assessment 3. A 'streak' system that makes consistency visible 4. Specific consequences for missing commitments (that actually motivate you) 5. How to recover after falling off without abandoning the goal 6. A 'pre-commitment' strategy for your weakest moments
最適な用途: CLAUDE
Claudeは最も持続可能なアカウンタビリティシステムを設計し、罰則ではなく習慣とインセンティブに基づいたアプローチを提案します。
テスト済み Feb 15, 2026
プロのコツ
アカウンタビリティパートナーを見つけましょう。AI は素晴らしいプランナーですが、実際に責任を負う人間のパートナーの方が行動を促す力が強いです。
長期的なビジョンを明確にする
Help me create a clear vision for my life in [3/5/10] years. Current situation: [brief overview of where you are] Areas of life: [career, relationships, health, finances, location, lifestyle] What's working well: [don't want to change] What's not working: [want to change] Dreams that feel impossible: [your biggest aspirations] Values: [what matters most to you] Create: 1. A vivid 'day in the life' description of your future self 2. The 5 biggest gaps between where you are and where you want to be 3. Which gaps to close first (sequencing matters) 4. The identity shifts required (who you need to become, not just what you need to do) 5. A reverse timeline: working backward from the vision to today 6. Three beliefs you hold today that might need to change
最適な用途: CHATGPT
Claudeは最も思慮深いビジョニングプロセスを導き、表面的な目標の裏にある本当の動機と価値観を引き出します。
テスト済み Feb 15, 2026
プロのコツ
「10年後どうなりたいか」ではなく「10年後の理想的な普通の一日はどんなものか」を考えましょう。具体的な日常の描写がビジョンを実行可能にします。
目標に向けた進捗を追跡する
Help me build a tracking system for my goals. Goals: [list 2-4 goals with current status] Tracking frequency: [daily / weekly / monthly] Preferred tool: [spreadsheet / app / journal / Notion] What I've tracked before: [past systems and why they failed] Data I want to see: [what would motivate you] Build: 1. A tracking dashboard layout with the metrics that matter most 2. A daily input form that takes under 2 minutes to complete 3. Weekly and monthly rollup views that show trends 4. Visual progress indicators (what charts to use and why) 5. Alerts for when you're falling behind pace 6. A 'wins journal' format to capture non-metric progress
最適な用途: GEMINI
Geminiは最も視覚的で使いやすい進捗管理システムを設計し、モチベーションを維持するマイルストーン設定が優れています。
テスト済み Feb 15, 2026
プロのコツ
進捗は毎日ではなく毎週チェックしましょう。毎日チェックすると、日々の変動に一喜一憂してモチベーションが下がります。
放棄しかけた目標を復活させる
I started working toward a goal but I've fallen off. Help me restart. Original goal: [what you set out to do] When you started: [date] When you stopped: [date and what happened] Progress made before stopping: [what you accomplished] What derailed you: [be honest] Current feelings: [frustrated / guilty / indifferent / motivated to restart] Create: 1. An honest assessment: should you restart this goal or is it no longer aligned? 2. If restarting: a 'restart protocol' that's smaller than the original plan 3. The minimum commitment to rebuild momentum (embarrassingly small is good) 4. Environmental changes to remove the friction that derailed you 5. A 'restart conversation' with yourself (reframing failure as data) 6. A 2-week ramp-up plan before returning to full intensity
最適な用途: CHATGPT
Claudeは最も共感的な目標リカバリーアドバイスを提供し、失敗を責めるのではなく、なぜ目標が停滞したかを理解する手助けをします。
テスト済み Feb 15, 2026
プロのコツ
目標を縮小することは失敗ではありません。非現実的な目標を現実的なものに調整することは、賢明な判断です。

Gemini
Best for structured planning templates and tracking systems. Creates quarterly plans and progress dashboards with built-in formulas for Google Sheets and Notion.
結果元: Gemini 2.0 Flash · テスト済み Feb 15, 2026ChatGPT
Best for vision mapping and goal restart protocols. Writes emotionally resonant future visions and handles the psychology of goal abandonment with empathy and practical solutions.
結果元: GPT-4o · テスト済み Feb 15, 2026Claude
Best for SMART goal refinement and accountability systems. Pushes back on unrealistic goals and designs systems that account for human imperfection rather than assuming perfect willpower.
結果元: Claude 3.5 Sonnet · テスト済み Feb 15, 2026Grok
Delivers anti-fluff goal frameworks with brutally honest reality checks about what is achievable. Excellent at cutting through wishful thinking, but less supportive in building gradual confidence than Gemini's encouraging approach.
結果元: Grok 2 · テスト済み Feb 15, 2026Write your goal as if it's already happened. Instead of 'I want to lose 20 pounds,' write 'I weigh 160 pounds and feel strong.' This framing activates different neural pathways and helps AI create more vivid, motivating plans.
Goals need verbs, not nouns. 'Get healthy' is not a goal — it's a wish. 'Walk 8,000 steps daily' is a goal. If your goal doesn't contain a specific action, ask AI to add one before building a plan around it.
Review goals weekly, not just when you set them. Goals you set and forget get abandoned. A 5-minute weekly review keeps goals alive and lets you adjust course. AI can generate a weekly review template in seconds.
