I understand! Somedays I do skip the eye exercises because I really want to scan this board or read emails. I feel guilty at times, but it's the best I can do.
I try to push myself when I can because I was told that one should work as much to our threshold to forge new neural pathways and exercise the nerves/muscle groups.
This doesn't minimize the pain, fatigue and shear exhaustion of these seemingly simple exercises.
Just do your best- you can't just be all work (exercises) and no play (iphone etc). I keep thinking of the marathon vs. the sprint analogy.
