People cry because of various emotions: anger, sadness, guilt, regret, or even happiness; sometimes they cry because they are so happy. I often see such people who, in most cases, had been trough hard times and overcame something, achieved something they had longed to gain for years. They grew as individuals.
Crying is not a bad thing at all; it can help purge you of undesirable feelings. If you want to cry, then cry. But you can't spend the whole life crying and crying. You just need to move forward to live a life that won't waste your tears.
Crying is not a weakness. It just means that you are facing the reality rather than avoiding it.
It is a tool to open a door. The key to success, the key to open the door. It can open the future, the unknown, the impossible, that you have never seen before.
It also can be associated with a human relationship because if you don't accept others, they won't either. If people accept each other like when a key matches the door, then they can bring their relationships to the next level. in this sense, I think the "key" to be successful in every relationship is acceptance and trust.
If you don't have them, others will not trust you back unless they have the right heart to love you unconditionally. Most people don't.
