When a client asks what I charge, I panic and blurt out a number way too low, terrified they'll walk away. Then I'm halfway through the job, working nights and weekends for pennies, quietly furious at myself for undercutting my own work. I never know what I'm actually worth, so I keep selling myself short and stewing about it after.
More people experience this than they realize.
You don't know what to charge, so you lowball yourself and resent it.
