Next, Adult, Parent, Your-Next, Your-Adult, and Your-Parent, each always capitalized (cf. Now)
Next denotes that part of every human being whose job and interest it is to take care of our future (both near and far) for that person, to have the future be good, where there is more happiness and less unhappiness (and pain) in the projected future. This is the part of us that imagines, makes promises, makes plans, and lives in the intention, hope, and anticipation for our future. It also can live in worry, anxiety, or dread that our future will be bad (unhappy). Whenever wanting to indicate more specifically the Next as that part of yourself or that part of another person, you can denote that part more clearly by using that person’s name in the word construction, as an example, Dwight-Next (denoting my Next).
An exact synonym of Next (especially in relationship to Now or Child) is Parent (meaning the parent of the child that is a part of you, regardless of how aware and respectful you are of that child). Any construction using "Next" can also use "Parent." For example, Dwight-Next and Dwight-Parent mean the same.
Your-Next is used to denote your Next (as distinct from anyone else's Next and from the Next that refers to everyone's Next). Similarly, Your-Parent would mean your Parent.
Usage example: Her Next thought she should study for her test for another hour. But her Now wanted to chat with her friends.
