One should learn to just be aware of things without feeling the need to change them. So often we look at something -- or someone (even ourselves) -- with the feeling that we need to change the situation or the person. Life will be less stressful if we simply look at things and people as they are - without trying to change them.
Most of us want to control things rather that simply be aware of them. We make judgments as to whether something is good or bad. Isn't it more relaxing when we learn to just observe without passing judgement.
It's like falling asleep. You create the "right" conditions, and then you "let go." Trying to force yourself to fall asleep usually makes you more awake.
