Using Rmcnew's theory on how the perceiving functions work I have thought of my own theory on how they can correlate to how someone with a certain perceiving type may live involving time as an issue.
Introverted Intuition :
Anyone with this as a function will live completely for the future. Their actions are always done in advance to prepare for something that could or usually will happen. They often think about the future and have ideal goals set up for themselves. *They also worry about the past very frequently and use it to aid them for the future, though it could cause harm if they repeat the same mistakes.*
Extraverted Sensing :
Anyone with this function lives completely for the present. Their actions are always done in the moment and they will only think of the present and may think of the consequences of their actions, but don't care. They live on a day by day basis and it makes their lives rather productive as a result. *The past does not matter for this person and may even ignore people they knew in the past as if they never knew them for this reason*
Extraverted Intuition :
This function is mixed and have aspects that are for the future and the present. This person will dream of the future and have ideal goals to reach that may or may not be fullfilled. They act in the moment and are aware of the consequences and think about it, though their impulsiveness may let them give in. *This person will worry about past mistakes and may or may not learn from them. The problem is if that the person does not learn from his/her mistakes, it will cause significant trauma and depression. They may also give themselves a fresh start if too many problems were experienced in the start and will have hope that things will get better from now in the future.*
Introverted Sensing :
They act for the future, but think of the present. If that makes any sense, they will do things in advance that will help them in the future because they know what is important for them in the long run. However, they don't have ideal goals and will often only think about the issues in the present. *These people often think about what they did in the past, but in a different manner. Instead of worrying about it or learning from it, they use it as memory to cycle through that could yield positive or negative results.
Introverted perceivers know time well and use it to their advantage when dealing with the past, present and future.
Extraverted perceivers often don't care about time and may make decisions that will hurt them in the long run.
Sensors think of the present and deal with issues only when they show up instead of trying to solve them beforehand. They act well to present problems though.
Intuitors imagine the future, worry about the past and like to solve problems before they start and have ideal goals for themselves.
I think I have made some mistakes here and there, but rather than dismissing this, I would like people to elaborate on my connections further. Basically, I am dismissing the fact that intuitive people completely live for the future and sensing people completely live for the present because I feel it is more complicated than that. Living completely for the future or present involves acting and thinking of either the present or future. Ex. If you only act for the future, you are planning for it, not living it.
Of course an extraverted sensor might live for the future/worry about the past one time or another and an introverted intuitor might live for the present occasionally due to the fact that the other weaker perceiving functions might come into action at random occasions.
