i know i am not in the same industry as you are but i was in the same boat as far as working for some one else my dad is a general contractor growing up as a self employed family and the flexiblity it allows you to have with your family and many other things i finally got tired of working for some one else and used my boss as a pay check while i pulled my license then quit i quit my job bought a house and had a baby all at the same time it was tuff it has taken me about a year to get things some what normal i think if this is your desire to be on your own maybe use the other job as a stepping stone to get where you want to be in life i am only 23 years old my wife is a stay at home wife and helps me in the office side of things hopefully things work out for the best for you good luck
