It is all about perspectives: if you chose to see the life through positive lenses, life itself will become positive, and all its aspects will shine in the colours of the rainbow.
By choosing the positive aspects of life, you eliminate all the other possible emotional spectrum.
It does not mean they will not exist anymore, or that you will be in denial or that negative moments will never happen again; it only means that you chose to perceive them from the opposite perspective.
