You can only trust yourself. Maybe I'm paranoid, of course, but trusting other people is quite dangerous, and often this risk does not justify itself.
Trusting yourself is good because there is no one in today's age who can bear your success but before getting experience you have to hear the words of others. I think it's not bad to ask about anything which you don't know but try to research from different sources and different persons after that take step by keeping conclusions in your mind.
Trust become difficult these days because every other person is in hurry to be more successful than another person and no one wants to help each other. Sometimes people shows that they are helping others by providing information but actually they are spreading wrong information because of making a way of getting cash.
