I trust people.
For the small things in life, it helps me, definitely, but when it comes to larger things it is an issue.
For instance I recently started to search if I could buy a house. I am not rich so for me it means credit. So basically if somebody sells me something which is not honest he could put me under debt and therefore make my whole life very complicated.
Personally I don't want to change, I still want to trust that people naturally are honest.
When somebody tries to sell me something, why should I think: 'is it right? are you not trying to rip me off?' instead of 'I believe this is the price of your work, let's see if we can accommodate it together'
when somebody gives me something, why should I think: 'is it all right? am I not abusing his kindness?' instead of 'Thank you! I trust what you give me does not cost to your life'
when somebody ask for help, why should I think: 'could he be lying? is it just to abuse the kindness of people? ' instead of 'If I feel good helping I will, otherwise I won't?'
why should this change?
I am not looking for a personal opinion more for readings together with some quotes or references.
