Is it true that two heads are better than one?

Definitely it's true that 2 heads are better than 1. You get alot of ideas, gain a lot of insights on the experiences of other people, a response can trigger more discussions and creative thinking would revolve. You just have to weigh what are important to you and which ones would be helpful. It's like you are making a check list based on the comments of other people and you only use those that are reasonable. Having more people to discuss some issues can help you create plans and strategies.

Too this question I would say it could be. It all depends on who the other person is and if they know how to slove the issue. If you know more than the other person and you do not know the answer you are in an aweful fix, so if the person is able to benefit you, yes two heads are better than one.
