Just. Do. It.
Even if you "out price" your worth, as some call it, 1 of 2 things will happen:
1) You'll experience a lul and some frustration, and you'll do nothing but sit idly and burn, and eventually quit or drop down in price again and "accept it".
2) If you're stubborn and driven as you raise your price you will equally spend time to do what you gotta to to get where you have to get asap.
You will continue to invest in yourself and your education and business at an accelerating rate.
Aside from considering what it costs to stay in business, and natural business costs,
When I consider pricing I also consider "what is $xx worth".
(in terms of what the customer spends $ on regularly)
What is $75 worth? A Video game? A few DVDs? A date night?
What is $150 worth? A cell phone bill…, Cigarettes, months worth of junk food, cable TV bill, pair of nice jeans, sneakers, iTunes …
you name it…. this is what the average person values and spends money on, at least in part
Do you feel the service you provide is worth as much as those things? Do you feel that what you do can impact someone's life equal to the above mentioned things?
(hint, it should be)
