What if we said "yes" to everything?

It depends on the situation. There's no right answer in this but I'd say, it depends. Of course, if it's something that's going to cause you harm, you shouldn't say "yes". I think people should be more open minded and learn to experience new things that will do them good but as far as saying yes to everything, no, I don't think so.

The thing is I think it goes both ways. Some people that are more uptight need to start saying yes more often whereas there are a ton of people that need to say no more often. There are people that constantly say yes in life and therefore they get run over by other people.

As in other things, I personally think life will be boring with all of the same thing. It is not possible to say "yes" all the time because that would, in a way, make people "robots" out of themselves. There are things that will reap bad and negative results by saying "yes". If I tell someone to kill somebody and he says "yes", you can just imagine what this world would become. We should learn how to say "no" to assert something that we don't like. It is exercising our right to deny or negate something.

yes yes yes yes we should often use this in situations where we cant use this we must learn the art of saying no :)

if you would say yes to everything then you would have no time for yourself as well as you will become a blind believer who has brain but whose actions are predefined to be yes and no other answer would be expected from you thus no one will talk to u as people will become bore out of you and use yourself for their own functioning this might lead to a harmless disaster.
