i have a better descrption.

problems of different dimension can occur at the same time. therefore, a lot of people get confused because of this. they can see up to up dimension at most.

you have to read alot think alot and experience alot to know and rememebr the different dimensions of problems that are occuring so you can recall the different theroies and solutiona assoicating with them.

physical body(headache)
realistic( outcome of the test is uncertain)
another level of realistic (your behavior, beliefs and feelings is still uncertain although they are nearer to your locus of control)
use imagination to learn more things, to produce more solutions ( work first, play later when you make yourself more efficient)
know the limitations of your ability( you will die, your vuleanrablities)
