Although Joseph Stalin was known to be heavily paranoid, when he said that he trusted no one, even himself, it was relatable. Trust is a delicate thing and everyone should prove themselves before earning it.
If you go around readily trusting everyone you encounter, you will be heartbroken and disappointed a lot along the way. Everyone is not to be trusted. Most people don't even know the meaning of trust.
You could pour out your deepest sorrows and heaviest secrets to someone, only for them to share it all the moment you leave. Sometimes your own family and closest friends will be the ones who stab your back.
After all, they are the people close to you and the ones who know you best. They are aware of where the shoe pinches you most. The world has become more volatile. Be careful with who you tell your secrets.
Be wary of people who readily tell you other people's secrets. If they can easily do it with you, they can just as easily tell others your secrets. Trust is generally a very big gamble. You can never be sure who will turn on you later.
So, take your time with trusting anyone. Never be in a rush to put such a big responsibility on someone's shoulders. Remember, the devil was once an angel. And even your own shadow leaves you when it gets dark.
Don't be gullible and naive. Take everything you are told with a pinch of salt. Watch people closely and pay attention to the way they act when they are around you and when you are not around them too.
Overall, lean more on yourself and trust no one. When you do, you will not have to worry about who will spill your secrets or turn against you tomorrow. Here are quotes to encourage you.
