When we think of negative and positive it is easy to think of it as black-and-white but this is not strictly true. As a coach for many years I pushed or tried to change people into thinking in a positive manner, no harm to this of course because being positive is beneficial to our well-being, in fact I often spoke of having a choice on how you view something, you can see the negative or you can see the positive and for the most part looking at things in a positive way tends to lead to a better outcome.
However much that I encourage positive outlook in life it should not come at the expense of ignoring negativity. Negativity is a balance and I have spoken about this in the past, it is important to understand that there are both sides to any thought process or outcome. It would be wrong to blindly ignore some negative thoughts as they can act as a warning and should be heeded.
So, it pays to understand that negativity also has its place in our thought process, we ought to be taking note of it but not allowing it to control us, in fact if we use it properly it can lead to us seeing a positive outcome from what would be a negative situation.
