A happy life is created by a clear understanding of “what works” and “what doesn’t work.”We shouldn't try to "make" something work that, by definition, "doesn't work."We should show wisdom — and then in our life there will be no reason for strong feelings and indignation.Wisdom to “accept what is happening.”Wisdom to influence in time what we can change.And the wisdom to distinguish the first from the second.So, how to wake up with a smile every day?
