Day 99: Build a decision matrix you can challenge.

A decision matrix is useful when the tradeoffs are visible, not when the table merely hands you a winner. Paste this prompt: "I am choosing among [OPTIONS]. First, ask me for the criteria and a weight for each criterion, with weights totaling 100%; then ask me to score every option from 1 to 10 on each criterion; build a weighted decision matrix; show the arithmetic for every weighted score and total; identify the criterion driving the result most; rerun a sensitivity test with that criterion's weight reduced by 50%, redistributing the difference proportionally across the other criteria; compare the rankings, state what changed, and flag any assumptions or missing information; do not make the decision for me."

Replace the bracketed text, answer the AI's questions, and check that each weighted score equals score multiplied by weight. Then challenge the result by looking at the 50% weight reduction: if the ranking flips, your choice depends heavily on that criterion; if it holds, you have a more stable comparison. You will finish with a ranked table, visible arithmetic, and a clear view of which assumption deserves more thought.

Tomorrow, I will show you how to find the story hiding in a small spreadsheet.

Day 114: Use AI to improve your time management skills effectively.

Start by listing tomorrow’s fixed appointments, three important tasks, and the hours you can actually work, then paste this prompt into your AI assistant: “Build a realistic schedule from these appointments and tasks; rank the tasks by urgency and impact, estimate a time block for each, add short breaks,

Day 113: Use AI to enhance your brainstorming sessions for better ideas.

Brainstorming improves when AI is given a clear problem and several roles instead of a vague request. Copy and paste this prompt: “I am brainstorming [goal or problem] for [audience]. Generate 15 ideas in three groups: practical, unconventional, and low-cost. For each idea, explain the benefit, the main risk,
