It is very easy to get cought in the demand of your industry like they have said. Too much without the proper understanding, work flow, ability and understanding that you are probably understanding how long it will take to do an adequate job.
Another point in my industry is spending all of your capital on equipment and consumables before a proper customer base is astablished. Too many times have I seen shopes start strong and then as soon as a slow spot hits(witch it will not matter how you plan for it) end up barred is equipment payments and go under.
Grow with your customers.
