I'd go one step further, "Make Something People are Asking For"
If you're making something people want, but don't yet know they want, you might be tempted to raise investment first.
If you're making something people are already asking for, you won't have much time for VCs. You'll be too busy fulfilling the customers who are knocking your doors down.
Sometimes it's nice to see someone say something that oughta go without saying.
