Repeat business and clients

I think everyone would agree that doing business repeatedly for certain clients is a lot easier than going out and getting new ones.  The two projects I have going now are just that....one is kind of an ongoing project that my friend recommended me for and the other is from me contacting the client directly asking if they needed any work done. Not all my former clients needed work, I often got the response that they will contact me when they did have some, however, this one said yes, and here I am in the middle of translating a 6000 word document! I try to outdo myself when I have a repeat client.  I certainly don't want them going elsewhere.  Constant improvement is a definate must in this industry.  Of course I will continually be marketing myself and contacting and networking but it is nice to know that their are people out there very satisfied with my work!  It makes it all worth while to me!
