Your questions are confused. Level 2 is a state. If you want to talk about 
states causing things, I suppose we can bend our thinking in that way, and 
the answer would probably be yes, but it wouldn't be the point of view I 
would take.
My book GETTING PAST OK is all about making the transition from Level 2 to 
Level 3. To answer your last question honestly, no, I don't think it's 
possible to have an extremely fulfilling and enjoyable life in Level 2, but 
it is certainly possible to give that impression to other Level-2ers. This 
is based on my personal experience with hundreds of people I have worked 
with in personal-growth seminars. I don't know how you could create a 
scientific experiment to measure quality of life that would satisfy an 
arbitrary level of skepticism.
