Before starting with a new client, I always run through a quick 5-point checklist. Helps me spot red flags early and keep projects smooth: 1. Do they have clear goals for the project? 2. Is their communication direct and respectful? 3. Do they understand timelines and boundaries? 4. Are they open to expertise, not just direction? 5. Do their expectations match their budget? Bonus - Did they work with a previous designer that just "didn't get them"?
