Balance and Disappointments

Disappointment! Everyone knows the feeling. There is the form of being disappointed because of a situation or a person, but there is also the one where you feel like the disappointment. There are days where the latter definitely is the case. However, lately this 'day' has lasted a very long time. Wikipedia says that disappointment is the feeling of dissatisfaction that follows the failure of expectations or hopes to manifest.
I feel that the word misunderstandings or the fact of not understanding or not knowing should be included in one version of the description of the word disappointment.
There are many disappointments in life. Never forget that hope is still the key to success. Evan Esar says

"Hope is tomorrow's veneer over today's disappointment"

The feeling of disappointment can be felt as something has been stolen from you, as some injustice. I have heard it been described as a bankruptcy of a soul that expends too much in hope and expectations (Eric Hoffer).

I would rather live my life with some moments of disappointments, than to expect nothing so to never be disappointed. A life that is not lived will never make any mistakes, but will also never grow and develop.

But you can always stick with the dreams like Marilyn Monroe:

"Dreaming about being an actress, is more exciting then being one"

How are you supposed to have balance in your life? I just watched the movie 'I don't know how she does it' that is a great example of just this. She has the job, the husband, the children, her dream... You have to have your priority list straight. She noticed that if she focused on the wrong part of the life that includes 'everything'   someone always got disappointed. So disappointment was a constant companion in her 'perfect life' that included 'everything'. In the end of the movie she somehow ends up keeping all parts of her life, she just set a list of priorities and followed it to a t. Family of course being at the top - then getting rid of the ugly word disappointment. 

Everytime most people introduce a new part into their life, the question of balance will occur as an issue. I have seen many people close to me, including myself, becoming feeling a third version of disappointment. Disappointment in themselves. Always expecting the perfection and balance of their expectations to arrive on the first train while not understanding that there are usually bumps, overbooking, sidetracking, and multiple opinions on the way to a satisfied balance. Balance is acquired not automatically received.
