✓ Break work down — small tasks estimate far better than big ones
✓ Estimate as a RANGE or confidence ("2-4 weeks, 70% confident")

✓ Use history — what did similar work actually take?
✓ Involve the people doing the work — not just you
✓ Separate ESTIMATE from COMMITMENT (deadlines are negotiated, not guessed)
