Ambition vs Aspiration

Satisfaction in life is earned in every moment –
no ‘goal’, once achieved, brings lasting fulfillment.
Once conquered, it makes way for another.
Ambition becomes relentless pursuit of the next.

Should we exercise aspiration in place of ambition?
Who do I aspire to be?

Fulfillment seems to flow from living up to
my own expectations. In every moment,
continuously earned, as
demanded by every choice and act.
