expectation versus reality

Once Shakespeare had said: " I always feel happy. You know why? Because I don't expect anything from anyone."

Expectations always be hurt, that is the fact in reality world. Therefore it sounds clichè for a glimpse but then again I would like to share random positive vibrant to enlighten us.
"Be happy, enjoy every seconds of your life.
Think before you write and speak.
Responsible to yourself and others of what you give and did.
Be wise when you spend on something.
Forgive before you pray.
Careless to feel of what others would felt before you are going to hurt. Empathy and Sympathy.
Never give up to try before you decide to quit.
Live it up, be alive and cherish every moment of your life because the essence and energy inside each of us does not only belongs to us, it is a blessing and need to share with others and nature."

Sometimes expectation is not always define in bad way . Do you agree if expectation is one of the way to achieve good thing in life?

Expectation same thing with a standard and have its various limitation and classifies.
As time goes flies, time takes time and as an adult we were not only learning for somewhat life measured by its abstain colors to drawn hence sometimes a natural stupidity teach us that life without load of expectation is the best way to live a life and leave nothing on the table:)
Please share your thoughts it would be valuable for me.
Thank you. May peace be with you, always.
Cheers-maria.
