Most consultants know they are worth more. But that doesn't make them worth more. The amount you are worth is the amount of money you will accept. Not the amount that you want.
If I told you you had to double your fees...most consultants would say 1 of 2 things.
1) But how can I get away with doing that?
2) I would lose half my clients
You would not be "getting away" with it. Nor is it a crime to charge high and be paid fairly for the value you provide.
Let's say you do lose half your clients. You would be making the exact same amount of money and be working half the hours.
Double your fees. It's literally worth it.
