As a business no matter how big or small you always want to grow. In order to grow you have to be able to reinvest a portion of your profits. If your bottom line keeps getting hit the rate of growth will slow. I will say that I am fortunate to not have any investors, lines of credit or loans. 
I agree... you are very fortunate. 
Your life is not bad at all. 
I think you see where I'm coming from.
