Dont always believe what you hear

Its so hard to determibe wether or not someone is lying or telling the truth. Some people dont listen to what other people say and wait to find out on their own and some just go by that others say. Well as for me i listen to what other people say and it always gets me in trouble, im still trying to break out of that habit but i find it very hard to do.. Im hoping that as life goes on i become more independent and not dependent and not rely on what other people say.. in my opinion i dont think someone should always listen to their friend, they should try to find out the truth on their own because somethings are not what it may seem to be..
