Most custom GPTs are useless because people skip the setup.
Here's how to make one that's actually helpful:
1. Start with ONE specific task. Not "help me with marketing." Try "write LinkedIn hooks for financial advisors." The narrower, the better.
2. Feed it examples of what GOOD looks like. Copy paste 5-10 real outputs you've liked. This is the cheat code most people skip.
3. Add constraints. Tell it what NOT to do. "Never use buzzwords. Never start with 'In today's fast-paced world.' Keep it under 100 words."
That's it. Took me 10 minutes to build one that writes better hooks than I do.
