[YourSelf]

...what would you do during your time left?

This is a question I often come across in texts about time management.

I personally think that 5-10 years ago I would have replied that I would do something really incredible in these six months, such as learning to fly a plane and do aerobatics with it.

But now (I'm in my early 20s) I think I would answer to the same question:
"Dunno, whateva..."

Have I become realistic or have I become apathetic/lazy? Or could it simply be that I feel I have already done enough things in my life, am satisfied and have seen the whole world?
(even if it's not objectively true, i.e. I have never married, never raised children, nor a family... I feel fulfilled.. as if there's nothing left to explore)
Perhaps I have lost the excitement in new things...?

In such case, isn't such [over-]satisfaction somewhat negative?
