“What do I really want?” is such a difficult question to answer. The fact is that most of us don’t know what we really want. And this target is a moving target anyway. Perhaps you want your own three bedroom house. Once you achieve it you might want a five bedroom house. Once you get that you might want a car, a relationship, a cappuccino a whatever….
Humans are meant to have a moving target in life it keeps us sane and interested in life. So don’t worry if you don’t really know what you want from life. Take a guess and go for it. It might be that after doing some research you find out that this wasn’t what you really wanted but at least you know that you are choosing to not pursue this goal rather than having it being chosen for you.
