Trust

Yes this world is of some fake people
and keeping trust on anyone is warning yourself .
Be agile when you are trusting someone
Because trust is brittle for the fake people
Don't be credulous
Be redundant with that trust breaking people.
No need of being tenacious with that people
Because this people are defamatory  
You be philanthropist
But don't be a heart breaker
Be geniality with everyone
But don't be a scammer
People are not durable in trust
So it's really better to do not keep trust on anyone
If you want to trust someone than trust yourself because you are better to trust, love ... Yourself
