"reasonable expectations spark productive experiences creating tranquility."
(friend)
YES when I work with clients- esp. student-athletes I have them make SMART GOALS
Specific
Measurable
Attainable (similar to key pts in article you sent)
Realistic
Timely
ANYONE needs to set goals that are specific to the place they are and relative to where they REALISTICALLY see themselves going in the short and long-term-micro and macro level goals.  GOALS set too high (and expectations too high) creates stress in many student-athletes and high achieving students- perfectionist...if you will....and goals should come from the PERSON not the parent, the CEO etc etc....suggestions from a mentor or elder is okay- but ultimately the person sets their own realistic and attainable goals. But realistic does involve WORK ETHIC- and sweat, effort, time management, smart choices, structure, vision, resources, motivation the list goes on and on- but basically BIO-Psycho-Social aspects of attaining goals :)....when recognized creates tranquility.
