TRUST. How important a Trust in Relationships?

Every day we are all have to deal in various attitudes of individual, situation and risks.
Commitment and Compromise were made by people from such agreements or dealings to earn positivity of somewhat achievement or goal for the sake of both parties or more.

Recently, I had been taught my very lessons about Relationships in work field, business and even personal life.
I do believe Chances may not always been given because of Distrust. Yes, consequently we must to accept certain worse things in life no matter what we would take it or leave it.
How if for real people would able to change progressively and the chance would be worth to be given even though the doors had been shut off.
Does Trust eventually will take win onto anything?
Please share your thoughts, who knows enlighten my views. Thank you. Cheers~Maria.
