What has life taught you recently?
Another thing I have got to learn of recent is that nothing last forever,not even power so it is advisable that we use every opportunity of power given to us very carefully and not to use it to oppress or bring them people below us just because will have power over them, power won't last forever that is why we must be careful of how will use it and not allow it to overwhelmed us,, nothing last forever as far as life is concern
"With great power comes great responsibility" - Stan Lee
It might be from Spiderman but it's a great quote.
