There are two things mainly to be considered. The first is her goal, the aim that she places before herself, not just in terms of few years but a few decades further. How and where she wants to see herself as she grows through the years. Secondly but as importantly, what are the activities and kind of work that come spontaneously to her, what gives her a natural joy. These are the two main things to be considered. To think about other things such as what will happen in the future will only confuse further as there is no certain way of knowing it. What is given to us is to think reasonably and act. The rest is best left to destiny and God.
Affectionately,
