I feel the same way. I've been working on my Associates degree for some time and have already said I will not be "walking" for graduation when the time comes. I don't feel I will have completed my education; only achieved a small goal along the way. I don't think it takes away any of the hard work or demeans any self-worth; in fact I think it shows your self worth because you are making a conscious decision to say my journey isn't over yet.
Congrats on all the exciting things going on in your life...it's fulfilling to achieve at any level.
