I am the sort of person who refuses to believe that someone who's rational all their life will be incapable of making sound decisions when faced with an emotional situation. If your left hemisphere has been dominant than chances are it's going to be dominant even when the right hemisphere threatens to revolt. Everything can be seen in its true light and given its right size, you just have to be brave and suffer for that courage.
You always know the right decision, but it won't be made if you let the right hemisphere overpower your judgment. So, to the right decisions, may they always be made no matter how hard they seem.
