Satisfaction is like the sky limit
the more you go higher to touch it, the more it goes further
but, ultimatley u will have progressed alot and acheived a height from the ground
Being satisfied lead you to no more progress
dont be satisfied, keep moving the target higher
I think that is a good way to look at it.
this is actually what I have learnt in my real life, when I compared people who are ambitious and who are satisfied, the ambitious are always risk taking, but they gain alot in life
Life is not only about being in safe side, it about acheiving
Cheers
well said
