A word or short phrase for the possible future state of one's life
If I read the implications of your question correctly, you seek a distinctive replacement for the rather generic title, "Personal Dream Life Coach." My response is directed toward a title that is more unique and personal. Additionally, because I realize that the occupation involves (among other things) enhancing a client's ability to visualize (via techniques like directed imagination, conscious dreaming, etc.) in order to actualize an ideal, fulfilling future life, I've linked some philosophical, metaphysical, and spiritual concepts related to IMMINENCE for you to consider, if you are so inclined.
A: Imminent adjective (imminent life guide or coach)
1 About to happen;
‘there was speculation that a ceasefire was imminent’
impending, at hand, close, near, approaching, fast approaching, coming, forthcoming, on the way, about to happen, upon us, in store, in the offing, in the pipeline, on the horizon, in the air, in the wind, brewing, looming, looming large;
threatening, menacing; expected, anticipated.
You will notice that "imminent" carries positive, neutral, and negative connotations (apparent in the above synonyms) highly dependent upon context.
