I think it is just a matter of semantics. While words have a meaning according to the dictionary, we all attach our own meaning to them, that meaning comes from our own experience and interpretation.
We can further identify such as "realistic hope". I have found myself doing that to clarify that I am not speaking of "wishful thinking" but of hope for the best case scenerio.
There is a quote I read but cannot quote corrrectly, but it said essentially this. (success is 90% planning and attitude and 10% action/work) I found that to be very correct in my most healthy period, before becoming the chronic pessimist I might be.
Hope does not mean that I am going to sit here and hope my ship comes in. If I apply for a job I really want, if I am not qualified, the situation would not be hopeful. However, if I am qualified and I want this job, I would be hopeful. I may be disappointed if I do not get it (as you described fonature), but disappointment is also part of life for everyone. That is a natural emotion we will all have, it is what we do with that disappointment.
So if I really want this job that is advertised and I am qualified and I apply, will the cover letter and resume differ if I am "hopeful" or if I am "not hopeful"? For me, I think it will differ, because I see the word hope more in the catagory of attitude than emotion.
There is a really good book that I need to re-read "the Secret", that talks about the power of intention. I have always found that my attitude has more to do with what happens to me than anything else.
If we dont expect much of what we want, we probably wont get much of what we want. I think we have to be willing to risk the feelings of disapointment, accept the feeling if it comes, and try again.
I also think there would be little success in any area without goals. If a depressed person comes to therapy to get better and the therapist just writes a note that says "I will assist patient in overcoming depression", and the insurance pays $75 per visit, if I were the insurance company that was doing the paying, I would want to know how the therapist plans on doing this. Are you just going to listen to the client until they are better?
More realistically, the goal :reduce depressive symtoms, objectives:1-assist client in identifying xyz
2-provide client with information that x
3-encourage client to abc
Many therapists have clients sign these treatment plans, some do not. Even those who do not, likely have a treatment plan in the file somewhere. It keeps the therapist accountable. It prevents them from loosing sight of why you are here for treatment.
Right now I have a problem with setting and following goals, but I didnt always, and was much better when I had written goals. Nearly every job performance evaluation has goals and objectives in writing.
